VERNOV, SERGEI NIKQLAEVICH (Physicist) 



S. N. Vernov was born July 11, 1910. He graduated from 

 Leningrad Polytechnic Institute in 1931. From 1930 to 1935 he 

 worked in the Institute of Radium of the U.S.S.R. Academy of 

 Sciences. In 1935 he went to work in the Physics Institute of 

 the U.S.S.R. Academy of Sciences, and in 1943 he became a 

 professor at Moscow University. He became Director, in 1946, 

 of the Scientific Research Institute on Nuclear Physics at Mos- 

 cow University. Since 1953 he has been a Corresponding Mem- 

 ber of the U.S.S.R. Academy of Sciences. In 1949 he was award- 

 ed a Stalin Prize. He was awarded a Lenin Prize in 1960 for 

 his participation in the discovery of and investigation of the 

 earth's external radiation belt and studies of the magnetic earth 

 and moon. 



Vernov studied the nature and properties of cosmic rays in 

 the upper atmosphere. He investigated cosmic rays with the 

 aid of automatic devices, elevated to high altitudes by pilot- 

 balloons and transmitting their findings by radio. Vernov and 

 his associates discovered considerable effects due to cosmic 

 rays in the stratosphere. They showed that the primary parti- 

 cles are composed of protons, studied transition effects in the 

 stratosphere and ascertained the origin of a soft component.
