"The composition of terrestrial corpuscular radioaction and possil-le mechanisms of its originif Lebedinsky, A. 'I., S. N. Vernov, A. E. Chudakov, I. P. Ivanenko Investigations conducted during the flights of the Soviet earth satellites and the cosmic rocket have yielded the following data on the composition of "terrestrial corpuscular radiation", that is, particles revolving about the earth: 1. In the outbr zone (1), the overwhelming majority of particles are electrons of energy 26 tO 100 kev. If we represent the energy spectrum of these electrons in the region of maximum radiation in the form: N ( E) l/E , then 5. Extrapola of such a soft spectrum into the region of lower energies shows that at F--5 to lo kev, the total density of electron energy would exceed the energy density of the map-natie fiald H2 /8- . For this reason, the electron spe-otrum in the region of law energies (several kilovalts) should either have a maximum or at least should be small at least in this region. The number of electrons of relatively high energies 5 X 106 ev) is negligibly small as compared w-ith the number of electrons in the 20-100 Kev range. The overall energy released in the crystal of the scintillation counter from photons due to the bremsstr2hlung of electrons is from, two to three orders of magnitude in excess of the energy released by all hi h energy particles that produce an energy release In the crystal of over 4.5 x lOg ev per particle. The total energy of all electrons in the outwe zone is approximately equal to the energy rel~9sed in aurorae during somewhat over one week. report presented at the International Cosmic Ray conference, Moscow, 6-11 July 1959 21(8) AUTHORS: Vernov, S.

TITLE: A Possible Mechanism of the Production of "Terrestrial Corpuscular Radiation" Under the Action of Cosmic Rays (Vozmozhnyy mekhanizm sozdaniya 11zemnogo korpuskulyarnogo izlucheniyall pod deystviyem kosmicheskikh luchey) PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 124, Fr 5, pp 1022-1025 (USSR) ABSTRACT: By "terrestrial corpuscular radiation" the authors mean the fluxes of particles moving in the terrestrial magnetic field along closed orbits. According to the authors~ opinion, the following radiation production mechanism deserves the most attention: Under the action of cosmic radiation, the earth, like any othercelestial body, becomes a neutron source. The neutrons traverse the magnetic field without being disturbed as uncharged particles and attain great distances from the earth. The charged particles originating from neutron decay move in the magnetic field along the lines of force. The particle Card 1/4 in the course of time reaches the region of high geomagnetic A Possible Mechanism of the Production of "Terrestrial SOV/20-124-5-17/62 Corpuscular Radiation" Under the Action of Cosmic LIFys latitudes, where fieldstrength increases considerably with increasing latitude. In this region the velocity vector of the particle will, as the particle approaahes the earth, turn so lone with respect to the vector H, until at the latitude X max the angle between the -4 velocity of the particle and the vector H becomes equal to 90c). At this point the particle returns and begins to move in the rear direction along the same magnetic line of force. If conditions are favourable, the decay products of the neutrons may perform 10 a and more oscillations between the northern and the southern turning points Therefore, the intensity of the flux of these particles increases by the same amount. Experimental data indicate the existence of such a radiation. The present paper carries out a closer investigation in order to find out by what factors the intensity of these rays is determined. Calculation is followed step by step. The Card 2/4 authors calculate the intensity of the "terrestrial A Possible Mechanism of the Production of "Terrestrial SOV/20-124-5-17/62 Corpuscular Radiation" Under the Action of Cosmic Rays corpuscular radiation" for various heights and latitudes; the results obtained by these calculations are shown by a diagram. They lead to the following conclusions: Although the number of neutrons decaying in the earth is very small, they may cause intensive cosmic radiation. The experimentally determined intensity is by -.100 times lower near the equator than calculated intensity, According to experimental data there is no terrestrial corpuscular radiation in geomagnetic latitudes above 400g but in the pre5ent paper j(X . 4,o) ,j(, - 00) is obtained,, This means non-agreement by moTe than 105 times the amount. In order to reestablish agreement with the experiment, it is useful to assume an additional flux of particles from "magnetic traps", which are particularly strong in large latitudes., This may be due to the existence of electric fields. This assumption also appears to be confirmed by the data concerning the considerable increase of perturbations of the terz~?strial magnetic field with increasing latitude, With increasing latitude, the interdictions imposed upon energy by Stoermer's theory Card 3/4 are being disobeyed to an ever-increasing extent, The A Possible Mechanism of the Production of "Terrestrial SOV/20-124-5-17/62 Corpuscular Radiation" Under the Action of Cosmic Rays mechanism discussed in the present paper mustapply also in the neighborhood of astrophysical objects having a magnetic field. Therefore, the investigation of this radiation in the neighborhood of planets may be a means of observing weak magnetic fields. The authors thank D, V. Skobelltsyn for his advice and M, S. Rabinovich for discussions. There are 2 figures and 7 Soviet references. ASSOCIATION: Moskolrskiy gosudarstverinyy universitet im. M. V. Lomonosova (Moscovi State University imeni Ia. V.

I.- TITLE: Hydrogen content in large planets PERIODICAL: Voprosy kosmogonii, v. 7, 196o, 50-54 TEXT: An attempt has been made by the author to explain the fact that the chemical composition of giant planets differs from that of other planets. For his purposes, the author assumed heating of the outer part of the proto- planetary cloud to have been caused,by the motion of solid components. A hypothesis put forth by him in 1950 explains why there.is an excess of hydrogen in planets starting from Jupiter# and lack of it from Mercury to Mars. According to this hypothesis, the protoplanetary cloud was composed of hydrogen and, possiblyp helium. Other elements were contained as small admixtures, Before thi6 cloud was subjected to a high pressure, hydrogen and all its.volatile compounds were in the gaseous phase. As condensation rose, dust began to concentrate in the equatorial plane, and formed a com- pact ring, like Saturn's, around the Sun. Because the Sun did not heat through to,the outer zones of the ring, the light gases condensed on the Card 0 Hydrogen content in.... 89063 8/555j6O/OO7/000/001/007 B123/B201 dust. The heated part gave rise to the planets of the terrestrial group on :the basis of sparingly fusible materials (rocks, metals) with moderate masses. The planets of the Jupiter group were formed from light matter adding to the dust. The various chemical compositions of the Jupiter group ~planets can only be explained by considering the energy equilibrium of dust at the periphery, where solar radiation was practically inexistent, and stellar radiation could not heat the dust to more than 30K- Under these conditions, friction was-apt to be the main source of thermal energy. The ,author has shown in two previous papers that the evolution of a dust system and that of a system of solid..47Wies exclude each other. The later paper has been published in the present periodical, Vol. 2, P- 5, 1954. When a flat disk, similar to a Saturn ring, arises# and the solid bodies act upon one another by gravitation, their volume is increased as the result of collisions of bodies of the subsystem. The equatorial diameter of the dust system is reduced by a decrease of the moment of momentum. The author considers the case where solid bodies and dust particles coexist in the sub- system. The energy of solid bodies is reduced by the friction on dust; it radiates into space as thermal energy. When bodies with comparable mass collide they are crushed in most oases# since, as a rule, their relative Card 2/3. 89063 .8/555J60/007/000/001/007 Hydrogen content in ... B123/B201 velocity is not less than several km/sec. The thus resulting small bodies go to augment the bigger bodies with which they collide, and the planetary bodies are formed on the expense of dust of the subsystem. Eventually# the disperse matter gets together to form the2planets. The heat set free in the process varies from 0.1 to 100 erg/am sea, depending on the distance from the Sun# and corresponds to a dust temperature of 5-300K. The process of planet formation takes place in two stages. In the first one, the solid component accumulates, and as the next stage, the chemical composition undergoes a change, once the planet has grown sufficiently massive. The gas density passed through a maximum at some distance from the Sunj this explains the maximum in the Jupiter - Saturn zone. Moreover, a monotonic dependence of the density on the orbital radius is observed with the Jupiter satellites. It is concluded that the planetary satellites as well must have formed under the same law. There are I table and 2 Soviet-bloc references. ASSOCIATION: Moskovskiy gosudarstvennyy universitet im.

This idea was later developed by V.D. Davydov. In the present paper the authors consider the amount of water present on Mars in free state; i.e. in the atmosphere or the polar caps. The amount of water is determined by estimating the upper limit of the amount of ice crystals in the Martian atmosphere from its turbidity, and the rate of evaporation of ice from the polar caps.

The photographs :also confirm the asymmetry of the moon relative to a plane dividing the near and .far sides.

A diffraction scanning qPVr,=-L- itrophotometer,,mounted on Cosmos-45~rccmprised the basic equipment. The spectrophotom- eter was esig-ned to measure thermal radiation in two bands, 7-20 P and 14-38 P. he spectral resolution for the first band ranged from 1.4 V for the 7-p wavelength;--- Ito 1.1 tj for the 18-p wavelength. For the second band, the range was from 2.8 It for Card 1 2962-M SION NR: AT5023566 the 14-11 wavelength'to 2.1 p for the 36-p wavelength. The instantaneous field of .vision of the optical system was 1*46' x 2*20', encompassing a radiating-surface area f 7.5 x 10 km at the average altitude of 250 km. The instrument was.capable of field of vision scanning within �8030'. Spectral intensity measurements-were carried !out at X= 9.5 � 0.6')j for the first band and X = 18.5 + 1.35 V for the second. Semi.- 1conductor 'bolometers with a sensitive area of 1 mm2 were employed as radiation sen- ! :sors.

To measure cloud cover below the satellite, a ,'Photometer operating at 6000-8000 A with a resolution of about 30 km was used. From the data obtained during the flight of Cosmos 45,the following.conclusions concerning ,the intensity of the Earth's thermal radiation were drawn: 1) The intensity at the !minimum of the absorption band near 15 )j is almost constant. 2) A close correlation between the intensities at the other wavel6ngths- was noted. This provides evidence P ithat the effective radiation levels differ but slightly for various regions of the !' !spectrum within 8-35 p. 3) The lower layers of the troposphere are the basic source _,of the thermal radiation leaving the Earth's atmosphere. 4) There is a strong vari, able intensity of the ozone band with its center at 9.6 U.'

Two hypotheses are advanced in explanation of the phenomenon: 1) the radiation comes from the surface of the planet which is heated by means of the "hotbed" effect in the atmosphere (see C. Sagan, Science, 133# No- 34569 1961), and 2) the radiation is created by the motion of ticles in heated and extremely rarefied layers of the Venuslan ionospheie a:artrop. cit. and D._E. Jones.

P IR spectrophotometer recorded thermal radiation concurrently with the operation of the other two instruments. A correlation was found to exist between readings of the UV and IR spectrophotometers in the 9.65-11 ozone band. A correlation of inter.,3i- ,ties was also disclosed near the long-wave boundary of the UV spectrum at A > 300-0 A land in the readings of the illumination sensor. These readings depended strongly on :cloudiness because the albedo of clouds in the red zone is substantially arenter than .the albedo of the Earth's surface and of the clear atmosphere. The correlation con- ,Eirms that at A > 3000 A, the noticeable part of atmospheric radiationis due to.tropo- .spheric dispersion and reflection occurring below the basic mass of the ozone layer. ,Conclusions were also reached on local, diurnal, and latitudinal variations of air- low. A difficulty'arose in the evaluation because of the dependence of the readings .9 on cloud cover. In.making the measurements in space, it was necessary to include re- flections of airglow from the atmosphere and glow of astronomical origin in addition ,to airglow itself. Consequently, results varied with atmospheric conditions by as much as a factorof two, with the minimum occurring during cloudless weather and the maximum during total.cloudiness.

The flight problems faced by Luna 9 and Luna 10 were similar enough but owing to a correction, Luna 10 i moved to a flight trajectory along which it approached the Moon to within a mintrnuni distance of 1000 kin. Dr. A. 1. Lebedinskiy discussed the special features of the i lunar landscape as transmitted on television, explained the structure of the space station and its operation when taking pictures, also the topography of the moon.' The objectives of Luna 10 were research on lunar space and lunar radiation. Academician S. N. Vernov, a specialist in cosmic rays, stated that tile Geiger counter installed on Luna 9 recorded protons, electrons, and gamma-quanta with I a strength sufficient to penetrate the hermetically sealed space station. Lunar radiation was found to be 10 times stronaer than that of tile Earth; it was found to be harmless to astronauts clad in space suits. Orig. art. has: 5 figures and I table.

The results have not yet been fully analyzed, and the data presented by the authors are only preliminary. Radiation in the two spectral bands was of different origin. The visible band was used to measure radiation caused by heat from the Sun being reflected by the Moon's surface; the IR band measured the Moon - radiated heat which was emitted by the Moon's surface, the temperature of which varies from -150 to +1200C. Infrared and visible radiation coming directly from the Sun also contributed to the total measured in both bands. Card 1/6 UDC: ACC NR.- AP7000546 A detector carrying two sensors (15 x 30-mm thin plates) mounted outside the Luna-10 body were utilized to separate different heat ra- .diation contributions (see I~ig. 1). The detector action was based on the variable resistance principle (i. e. , changes in heat radiation varied .the detector resistance). Detector resistance was measured by a cir- cuit (such as a resistance bridge) and the results of these measurements were telemetered back to Earth. One of the sensors was covered with enamel, which absorbed 85-95% of the incident IR radiation and reflected 70-751o of the radiation in the visible band, The other sensor was covered with thin gold foil, which reflected 97-9916 of the IR radiation and passed most of the visible radiation. Data taken simultaneously from both sensors will be used to isolate that portion of the total heat radiation which was contributed by the Moon. The satellite was rotating around its own axis with a period which was shorter than the detectors' thermal time constants, and the readings therefore represent the average values of thermal radiation. The sensors were sampled simultaneously every two minutes. Card 2/6 ACC NR, AP7000546 Fig. 1. Thermal radiation detector 1 - Heat insulator; 2 sensors; 3 - clamping ring; 4 stand* Temperatures measured by the sensors (A, with enameA! cover; B, Aith gold foil cover) during the 8th, 31st, and 49th measurement sessions are given in Fig. 2. In the 8th session the satellite crossed Card 3/ 6 ACC NR: A?7000546 from the dark to the sunlit portion of the Moon. During the 49th session, a crossing from the light to the dark portion was made. In the 31st measurement session the satellite was on the sunlit side of the Moon. -The time marks in Fig. 2 indicate Moscow time. As expected, the ,teiTiperatures on the light side of the Moon are higher than on the dark .side. During crossings the sensors registered corresponding changes in temperature after a time delay associated with their thermal inertia. The influence of thermal detector inerti 'a was investigated by taking temperature measurements at different instants during a single session. The instants at which Ithese measurements were taken varied from session to session. These readings are plotted and compared in, the figure,. illustrating the effect of thermal time delay on.the sensor -output. -From 2-3 May through i3 May the temperatures of both sensors .declined noticeably. The A-sensor temperature decreased by 22'C and that of the B-sensor, by 50*C. After 13 May the temperatures again began to rise. The speculation that this phenomenon is associated with the changing orientation of the satellite with respect to the Sun is -confirmed by the fact that the B:-Bensor, the more sensitive of the two to the Sun's rays, was affected more than the A-sensor.

The eve was ptit on a small gauze pad, moistened with Ringer's sulution and plact-d in .1 smill dark chamber. One chlorinated silver electrode was connected to tile Inar- gin of the cornea, the other to the back-pole of the eye near the outlet of the optic nerve. The currents in the retina were registered by the loop oscilloyraph. The indifferent polarizing electrode was connected to the gauze pad, the active polar- izing electrode was placed on the surface of the eve bulb between the electrodes connected to the oscillograph. The strength of tile polarizing current was 20-100 ;An. The electroretinogram taken during the illumination of the eye had been re- gistered before the switching on of the polarizing current, during its action and after the switching off. The following results were obtained: during the passing of the direct current and polarization by the anode a distinct lowering of all tile 3 peaks, W, 'B' and 'C', was observed; the lowering was, to a certain extent, proportional to the strength of the polarizing current. By polarization with the cathode a marked heightening of all the peaks was noticed. particularly of th~ peak W. After the switching off of the polarizing current, while polarizing with i the anode, a distinct increase of the waves was noticed, while, when using the cathode as polarizing electrode, a distinct decrease was noticed after switching off. The changes in the ERG. induced by the polarizing current, vanished only 3 min. after the switching off. The authors regard the results obtained as proof of the fact that the waves 'B' andC' of the ERG are the electrical expression of the activity of the ganglionic cells of the retina. The changes.observed in the ERG during the polari"flon of the retina aret considert4 to be chanires in the functional state of the nerve cells. Tron - Leningrad (XII. 2) LEB-DiINSKIY, A. V.
