SKOBEL'TSYN, DMITRII VLADIMIRQVICH (Physicist) 



D. V. Skobel'tsyn was born November 24, 1892. After gradu- 

 ating from Petersburg University in 1915, he worked in the 

 Polytechnic and Physico-Technic Institute in Leningrad. Subse- 

 quently he was at Moscow University and the Physics Institute 

 of the U.S.S.R. Academy of Sciences. In 1951 he became Di- 

 rector of this Institute. He was a Corresponding Member of 

 the U.S.S.R. Academy of Sciences from 1939 to 1946 when he 

 was elected Academician. Skobel'tsyn has been active in public 

 affairs also. He was Deputy to the U.S.S.R. Supreme Soviet and 

 a member of the Commission on Foreign Affairs of the Soviet 

 Union. In March 1962, he was re-elected a delegate from 

 Ural SSR to the Supreme Soviet. In 1950 he was made Chair- 

 man of the Committee on the International Lenin Prize " For 

 Strengthening Peace Between Peoples." He was awarded a 

 Stalin Prize in 1951 and in 1952 the gold medal of S. L Vavilov 

 by the U.S.S.R. Academy of Sciences. 



Skobel'tsyn carried out research in nuclear physics and 

 cosmic rays. In 1923 he began research on the phenomena of 

 interaction of substance with gamma rays from radium. In 

 order to clarify the mechanism of these phenomena, Skobel'tsyn 

 used the Wilson cloud chamber, with the aid of which he was 

 able to view directly and photograph the recoil electrons 

 knocked out by collisions of high energy photons (gamma rays) 

 with gas atoms which filled the chamber. These studies gave 

 direct support to the quantum character of the Compton effect. 

 Subsequently Skobel'tsyn utilized these phenomena for studies
