It was found that with a corsitant temperature of burning and equal duration of the preBence of coal particles In the combustion chamber completeness of wnbustion of aerosuspension and rate of combustion of the coal A -~ are practically independent of pressure. It has been demon- -us strated experimentally that 3teady combustion of anthracite aerosus- pension is possible at pressures up to 8 atm and considerable thermal loads.

ABSTRACT-. An ironless spectrometer of' alpha-.e noir--;idences with spatial focussing of electrons is dest;ribed. The instrument has a resolution of about 1% and an illumination of 7% (ele2trons). It can be used to study conversion lines with intensities of the order of -0-4 electrons per alpha-de-,ay. The construction of the spectrometer is illustrated in Fis. 3. The main part of the spectrometer is a toroidal- coil,,I, which produces the focussing field when a current passes throngh it. It consists of 800 copper turnE which are water-cocled,3. Currents up to 30 A can be passed through. the coll and electrons with energies up to 0.6 MeV focu3sed. The ccll Is placed in copper cylinder which is evacuated to a pressure o.f 2 x 10-9 mm Hg. Close to the source 18 placed a photo- Card multiplier, 14, which records alpha-particles. This phrito- 1/2 multiplier can be placed either below or above the A Toroidal.

Seriya fizicheskaya, Y. 26, no. 12, 1962, 1470-1474 TEXT: A P-spectrometer for investigating modes of decay using a coincidence method is described. Its principle parts are two toroidal coils, each weighing 400 kg, placed one above-the other and divided into 4 sections connected in parallel for cooling burposes. 'For each coil the distance between source and detector is 800 mm. Each coil consists of 600 insulated turns made of 0.7 mm stamped copper, which are assembled in 60 packages. They are symmetrical with respect to the median plane of the coil, connected in aeries., reinforced and cooled in the middle by 2 mm shoot brass provided with a water-cooled pipe. The dimensions and the resolu- tion of the apparatus are determined by the distance f between the source (detector) and the median plane of the coil, and by the coefficient k Card 1/3 S/048/62/026/012/003/016 A.double, air-core P-spectrometer ... B117/B186 from the equation p(oe cm) = 0.2 )(ni (A), where p is the momentum of electrons to be focused, i the current intensity, and n the nut 3r of turns. f - 400, '/ - 0.8 were chosen as being optimum values. Ii-e coils are contained in an evacuated case carrying coupter-turns on the outside to compensate parasitic fields which are set up when current flows )hrough the coil. A vacuum lock in the middle of the case permits installation of sources between the two coils when they are operating independently. Next to the lock there are Wilson seals for the rods connected with exchangeable diaphragms. Adjustable scintillation counters with st~lben~e crystals, mounted perpendicular to the axis of the apparatus on sep4rate flanges, serve as dete 'ctors. The coils are supplied from two current stabilizers controlled by d-c tube amplifiers. The power supply eyetem makes it possible to maintain a stabilized current of 3 - 70 a for continuous operation at 80 v, or 160 v with the two coils connected in series. Each of the earth's magnetic field components is compensated to 1/50 by 3 threefold coils, connected in aeries, which are fed by a stabilizer made up of transistors. Debugging the apparatus is very simple; it comes down to checking that the components are accurately made and correctly assembldd. With a 4-mm source and a 5-mm diaphragia, one section of the coil has a resolution of 0-45%- With an open diaphragm the Card 2/3 8/043/62/026/012/003/016 A double, air-core P-opectrometer ... B117/B186 luminous intensity almost attains the geometrical value of 10% of 4x; with 0.45% resolution, it amounts to 2%. The resolution with an open exit diaphragm and a 4-mm source is 1%. The decrease in luminous intensity observed when the resolution is increased is related to the fact that the electrons art) deflected in their trajectory by the stray field of the turns when they pass near the sections. -The deflection of the trajectory can be partially compensated by awitchiiig in the second coil. This was confirmed in the case of a 4-mm source and a 5-mm dis~phragm, with the second coil connected in series: the luminous intensity increased 1.5-fold and the resolution rose to 0-30%. The paper was presented at the 12th Annual Conference on Nuclear Spectroscopy held in Leningrad from January 26 to February 2, '1962. There are 4 figures and 1 table.

Seriya fizicheakaya, v. 25, no. 2, 1961, 274-282 TEXT: The present paper was read at the 10th All-Union Conference on Nuclear Spectroscopy (Moscow, 1960), and also at the 11th Annual Conference on Nucle- ar Spectroscopy (Riga, January 25 to February 2. 1961). It presents test results that have been obtained by the authors by using an advancedmethod of studying the spectrum of conversion electrons of Ra225. The investigations were carried out by using not only d-e K but also I-e K (spectrum of conver- sion electrons in coincidence with gamma rays) and e K-7 coincidences (gamma sDectrum in coincidence with the electron line). The conversion electrons were separated by means of a torroidal beta spectrometer of high intensity Card 1/ 7 S/048/61/025/002/012/Oi6 Conversion transitions ... B117/B212 (Ref- 4). The gamma quanta were recorded by means of a scintillation gamma spectrometer, which consisted of a NaI(Tl) crystal, an amplifier, and a one-channel analyzer. The measurements were made with a Th229 isotope wmc)r- had been obtained by chemical separation of thorium from U233 that had been stored for a long time. Two test series have been made. Fig- 3 shows the internal-conversion electron spectrum for one of the series. A list of the conversion transitions obtained by analysis of the conversion lines of Ra 225 is given in Table 2. Based on the results obtained, a new level scheme has been suggested for Rs.225 (FiS~ 4). The data found during the investigation of alpha radiation of Th2 (Ref. 2) are given on the left side of the scheme, while on the right side, there are the level parameters which had been found by analyzing the conversion-electron spectrum. It fol- lows from Fig. 4 that it had been necessary to introduce a new level around 25-3 kev telow a . This necessity arose due to a 25-3-kev transition with high intensity that was in a cascade with a 17.3-kev transition. Besides, the investigation of e,,-y coincidences showed that conversion electrons of 25-3-kev transitions (Fig. 1) and 42-7-kev transitions coincide with garms, quanta of energies of up to 200 kev. The necessity of intro- Card 2/ ? B/048/61/025/002/01 21016 Conversion transitions ... B117/B212 ducing a lovel below that of~ao agrees with results given in Ref. 3. Apart from the above mentioned level, also a level near a 214 had to be introduced. According to measurements, this level energy is 2 C-7 kev, with respect to ace Severul cascades confirmed -this value that hi-4 5een calculated for a direct transition: 17-3 + 193-4 a 210-71 86-3 + 1;e4-4 - 210.71 56.6 + 154.2 - 210.8. it i!9pointed out that the level introduced does not oontradict the existing TO spectrum since the resolution of the alpha spectrometor used was not high enough to determine an expansion of the a 214- line by 1.2 kev. The energy of the 86-3-kev transition is almost the same'as that of the a 88 bignsition that had been observed in the investiga- tion of tho alpha spectrum. It had to be classified as a transition from the 21^-.7-1:ev level to the 124-4-kev level since it coincides almost completely (about 8Wo) with the XK-raOiation. On the assumption (Ref. 2) that the a214 and a levels are the first two levels of the rotational 246 band, a transition of the type MI + E2 must take place with a considerable intensity. In fact, such a transition was established. Its energy is 32 + 0.7 kov and its intensity is about 5%- Spins and parities of levels Card 3/ 7 Conversion transitions 5/04Y61/025/002/012/016 B117 B2 12 (a. ~nd above) have been introduced on the basis of data on the multipolar- ity of transitions and intensities. The a 214 level with a spin 5/2 and a positive parity is taken as starting point. Studies of the spin and the parity of 'the level (a_ 25-3) and of the ao and a 20 levels and their assumed spin values led to the conclusion that the (a- ) level has a spin of 5/2 25.3 229 or 3/2 and a negative parity. In the alpha spectrum of Th no transition to the (a-, ) level could be found. This forbidden transition for an 25-3 alpha decay seems to be due to the fact that its -arity is opposite to that of other levels of Ra 225. The authors thank G. I. Grishuk, V. F. Xonyayevq Yu. N.
