Scattering amplitudes were investigated for their analytic properties in both elastic and inelastic processes as functions of scattering angles and as func- tions of the impulse transfer. The latter case was studied on the basis of the general principles of field theory. It-vas shown how the range of analyticity (depending on cos-L9) of the differential cross section of an arbitrary inelastic process can be expanded, making it-possible to obtain restrictions on the behavior of the inelastic cross section of differential-forward scattering at high energy. The character of the dependence of-apartial wave on the orbital moment vithin the rangeof high values of the moment vas appraised. 2/2 -1/2 009 UNCLASSI FIED ~R'OCF,SSING DATE--160CT70 JLTL'E_--THE BEHAVIOUA OF HIGH ENERGY FORWARD SCATTERING AMPLITWE -U- -.AUTHOR-103)-SAVRIN, V.I.v TYURINP N.YE.:, KHRUSTALEV, O.Z. ,'COUNTRY OF INFO--USSR iOURCE-~-TECRETICHESKAYA I MATEMATICHESKAYA FIZIKA, 1970t VOL 2, NO 3, PP '-338-342 ~'OATE PUBLISHED------70 -PHYSICS UBJECT AREAS TaPIC TAGS-SCATTERING AMPLITUDE, HIGH ENERGY PARTICLE, ASYMPTOTIC: -.-PROPERTY, HEAVY NUCLEUS - MARKING--NO RESTRICTIONS i'DOCUMENT CLASS--IJNCLASSIFIED ::PROXY REEL/FRAME--1985/1445 STEP NO--UR/0646/70/002/003/0338/0342 .CIRC ACCESSION NO--AP0101531 UNCLASSIFIED q g~p gjq, ft 2 121 009 UNICLASS IF I EO PP!.0CESS!NG n--Ar.E---lb0CT70 'ZIRC ACCESSION tNO--AP0101531 `A3STKACT/EXTRACT--(U) GP-0- ABSTRACT.

It is shown tbat the highest economic and technical op(aating indices for diamond chisels are achieved by applying a slmr-speed lar-pressure turbine of precision casting, namely the iTSSh-190TT, turboexill. and the 33/11 turbine.

"Intergranular in a Fused Zone of Welds Prodiiced by the Electric Arc Under Continuous and Pulsed Welding Conditions" Moscow, Fizika i nimiya Obrabotki Materialov, No 1, Jap/Feb 73, pp 120-123 Abstract: Uninterrupted welding of EI-435 alloY Vrith tunjrsf~eii electrodes in argon resulted in much more extensive slippage coinpared,vith pulsed velding. Slippage amounted to 1.094p, along the t~ransverse grain boundaries and 1-07/-L along the longitudinal boundaries Of the central axial crystallites. These figures in the case of ptilsed welding were 0 .720 and 0 -590 44, respectively. The higher slippage produced by continuous welding is attribuzed to (1) much higher internal stresses within the high-tempevature region, (2) slower cool- ing rate of the hardened metal, and (3) Mch =oother &rpin Ova-per~. The Intergranular slippage along transverse boundaries of crystallites grown next to the fused grains within the weld zone is larger than illong tine longitudinal grain boundaries.

Atrazine was more toxic in doses of 10-13 kg/ha, while the effect of diurone was cumulative in smaller doses and lasted much longer. Among plants teBted,,tnngerine tra4!s were the most resistant, and two-year old apple trees were the most sensitive to both compounds. Analysis of the carbohydrate content showed that it was only slightly-influenced by large doses of these herbicides (13-16 kg/ha). Sensitiveness of perennial plants to these herbicides depends on their age,. variety, and type. 75 W USSR 95 uDc 621.3, -11:621-3r(-3 G..

"Concerning the Meohanism of Failure of Gunn Diodes" Leningrad, Fizika i Tekhnika Poluprovodnikov, Vol 6, No 9, Sep 72, pp, 1670- -1676 Abstract: Devices based on the Gunn effect operate most effectively at high bias voltages; however, increasing the voltage causes b2-eakdown of the de- vice. At present there is no unanimous opinion on the mechanism of failure and degradation of Gunn diodes. In this paper the authors investigate cc- planar Gunn diodes with plane-paral-lel and annular electrode,configurations both with mid without a silicon dioxide passivating coating. The diodes were tested in the Dulse made. It is shown that in accordance with pre- viously available experimental data the failure of Gunn diodes takes place as a result of formation of a shorting channel between the contacts of the device.. Information is obtained on the dynamics of the visible portion of the breakdown by means a' motion picture photography of this process through an optical microscope. It is shown that silicon dioxide passivation of the 1/2 USSR CHIGOGIDZE, Z. N. et al., Fizika i Tekhnika Poluprovodnikov, Vol 6, No 9, Sep 72, pp 167o-i676 active region has an appreciable effect on the nature of the visible portion of the breakdown and on the ratio of the breakdown voltage to the threshold voltage. A microscopic x-ray analysis is made of the composition of the contact regions and the channel on various stages of thermal breakdown, It is found that a transverse magnetic field affects the position of 'the shorting channels and the ratio of the breakdown voltage to the shorting voltage. A study is made of Gunn diode emission in the irfraxed region of the spectrum at voltages close to the breakdown voltage. It is concluded that the cause of failure of Gunn oscillators at bigh bias volta3es is the formation of current strings caused by the development of an S-shaped current-voltage curve due to impact ionization when a strong field domain passes over the specimen.

The produ C, tion of titanium metal as well as the production of titanium dioxide place stringent demands on the purity of the tetra- chloride. uzed. as the. starting- ~materi al. technical TIC14 consists A of a very complex. non.-equilibTiJ 7 system -containing &any. minor onentsL.-. It contains a broad spoctrum of Impurities which are clearly determined by the nature of the starting materials and by the chlorination neth d 7Ito domestic industry produces the bulk of technical titaniun tetrachloride by the established technology. In accordance witj this tochnology, the titanium-containing 31ags orconceetrates F; are chlorinated In the presence of carbon-containing reduci r agents (petroleum or coal-tar coke) in shaft furnaces (in the form of I-riquets), or, preferably, in molten chlorldc5 of the alkali or alkaline earth metals (for example, In tile spent electrolytes from the electrolytic magnesium cells). As a rule the chlorination of titanium-containing raw naterials in nolten Its yields.,purer TIC14 than thatobtained by the chlorination tit electric haft furnaces. Thus, for example, on chloTination in the melt, most of the aluminum remains in the melt and is partially trapped in the condensation system as MoAlC1 wh I cli Q9 considcrAbly facilitates the subsequent purifLe ation ot the tetrachloride. involving aluminum removal. As a scconc~ example we may cite the sulfur-containing Impurities which are present in the technical titanium tetrachloride in quantities that are dnerxined not only by the sulfur content of the sturting mater 1 1, but also by the type of the chlorinating agent. 11 USSR 1] zt Ili c renii It I ng t cc It n I c a I -grade t it i it i um I ct rach In ri 14, 1 % a milk), (dur tothe pr~qttncv of hydrol~,sis prdurt~ and entrainc,l starting material) and fuming liquid that varies in color from yellow-green to dark red, depending on the quantity slid type of impurities present, The impurities found in the technical titanium tetra- chloride may be tentatively divided into three ba%tc groups depending on their physical form at the normal boiling point of TIC14 and their solubility In the totrachlorile: 1) Gases and vapor$ (02.

"Helium Pore Growth Rate in Irradiated Beryllium Oxide During Annealing" Moscow, Atomnaya Energiya, Vol 30, No 1, Jan 71, pp 54-55 Abstract: Beryllium oxide samples were irradiated at 70% in an integral flux of 5 x 1020 neutron/cm2 (E ) 1 Nev). To produce a concentration of helium atoms equal to approximately 1.2 x 1019 cd-3. nlese samples were then annealed at 1400 and 1500%. For samples annealed at 11,000C the number of pores observed increased up to 3.0 minutesg after which the num- ber decreased. However, the average pore size contlnu6lly increased witli time. At 15000C, 833 pores were noted at heating for 4 minuten while only 36 could be found after 15 minutes at that temperature. Again the average pore size grew with increased heating time. The assumptlon Was made that the pore growth was caused by the high gap pressure in them (5000 atm at 1400-1500%). Ilie grain boundaries (vacancy 'sources) had a great effect on-pore size. The mechanical stresses at-the grain boundaries, due to their anisotropic expansion during heating, plays some role. It is possible to conclude that in reactors at 1400-1500% almost sL1 the helium 1/2 USSR KH Atomnaya Energiya, Vol 30, Me 1, Jan 71, pp 54-55 will be concentrated in pores. Secondly, the helium piessure in the pores for each time interval of irradiation will be equalized by surface tension. These conclusions stem from the "act that development of pores from the moment of nucleation up to stoppage of growth occurs at.spec:Lfic tempera- tures in a very short time. The author thanks Z. Ye.
