Orig Pub : Zh. eksperim. i teor. fiziki, 1955, 29, No 4, 417-429 Abstract : A study is made of the state of a spinless charged meson field, interacting with an extended infinitely heavy nu- cleus. The solution of the Schroedinger equation for the systam is obtained by expanding in a series in powers of the reciprocal of the interaction constant g2j'hc ;-> 1. The scheme for the solution is illustrated by an analogy with the adiabatic theory for molecules. By way of two possible methods, the following is proposed- in -the zero approxLnation one neglects the kinetic energy if the me- son Card 1/5 USSR/Theoretical Pbysics B-6 Abs Jour Referat Zhlar - Fizika, No 5, 1957, No -LO931 field, sin!!e it is proportional to (g'/,tfc)o and consequent- ly is BMEL11 compared with the potential of the field and the enerty of Interaction, which is proportional to 62/lbc- With this, the meson field J,,, Is split up ijito the classical and operator portions: 0 E ).r- V, 11.14 C' P fo\ - 4 ~al x -t f -t The unpertxwbed Hamiltonian HO is an operator only relative to the variable s of the isotopic and ordinary s-pins of the nucleus.

Lot&, Vol 24, p. 645 (19511) the Coulomb's interaction leads in the perturbation theory not to the anomalous diamagnetism. It is shown in this context that also the magnetic in- teraction of the electrons in the framework of the perturbation theory does not lead to an anomalous diamagnetism. The relativistic Hamiltonian is the best choice for the quantized electromagnetiv field. In this context, the interaction of electrons (neither the Coulomb's interaction nor the magnetic interaction) is not introduced in its explicit form but rather is the result of the exchange of virtual photons (longitudinal and transverse).

Then the paper proceeds to follow step by stop the further oourse of the oomputatione. The magnetic interaction yiolds no anomalous diamagnetism. The terms of higher ordor with respect to q2 yield a correction of the usual diamagnetism. It is not nooQssa.ry to take intoiaocount the higher perturbation theoretical approximations for the magnetic inter- action. It appears that application of the perturbation theory to the magnefi- interaction is justified. (1 reproductio?l' ASSOCIATION: Moscow State Peuia6ogic Institute.

Received; 3 / 1957 Reviewed: 3 / 1957 ABSTRACT; On Ssptomber 21st 1956 Sun ZACHARCIVIC BELENIXIJ, a well-known theoretical physicist whose reputation is mainly based on his works on cosmic rays, died at the age of 411. B.Z.BELENIKIJ was born ip Moscow on the 14-June, 1916; after his leaving examination (1931) he worked two years in an electric -plant. From 1933 to 1938 he studied with great success at the physical faculty of Moscow uni- versity and worked from 1941 to 1943 at the Central Aero-Hydrody- namlo Institute. He then undertook a dissertation at the Physical Institute of the Academy of Science of the USSR and became the head of one of the theoretical sectors of this institute in 1948- BELENIKIJ wrote his first scientific work (on the scattering of X-rays) during his last university term. These works showed the author's aptitude for theoretical j,hysioal work. In 1938, as an aspirant at Moscow university, he vas able to concentrate his whole attention on the problem I.H.TAW had asked him to solve (theory of cascade showers in cosmic rays),, BELENIKIJ was able to deter- mine the spectrum of cascade electrons and this work served as a basis for his candidates' dissertation written in 1941. (Reviewer's comment: In the USSR there are canlidateal- and doctors, disserta- Card 1/2 In Memory of S.Z.BELENIKIJ. PA - 2053 tiona). In oonnection with the problems solved by experiments BELEHOKU undertook quite a series of further investigations, in which the development of the theory of cascade showers was practically completed. In 1948 his monography "Cascade processes in cosmic rays" was published. BELIVIKIPs works on the cascade theory are of fundamental importanoo. Though it is true that the investigations of the cascade showers form the main part of BELENIKIPs entire activity, they ware not his only domain of re- searchl he also dealt with hydrodynimic problems as well as with the hydrodynamic and statistical thoory of the multiple produc- tion of particles at high and superhigh energies. Recently BELENIKIJ dealt with the nuclear cancade processes and with the phenomenological theory of the scattering of nucleons by nucleons at high energies. For his merits in solving applied problems he was awarded the Lenin order and the Stalin prize. ASSOCIATION: Not given. PRESIMTED BY: SUBMITTED: AVAILABLE: Library of Congress. Card 2/2 GEYLIMON., B.
