VUL, BENTSIQN MOISEEVICH (Physicist) 



B. M. Vul was born May 22, 1903. He graduated in 1928 

 from the Kiev Polytechnic Institute. In 1932 he went to work at 

 the Physics Institute of the U.S.S.R. Academy of Sciences. He 

 has been a member of the Communist Party of the Soviet Union 

 since 1922. In 1939 he was elected a Corresponding Member 

 of the U.S.S.R. Academy of Sciences. He was the recipient in 

 1946 of a Stalin Prize. 



Vul's works deal with the physics of dielectrics. While 

 studying electric strength of dielectrics, he established the 

 nature of the end-effect in the breakdown of dielectrics and the 

 particularitites of the breakdown of compressed gases in sharp- 

 ly heterogeneous fields. He discovered (1944) a new ferro- 

 electric-barium titanate (BaTiOs) which has a very high di- 

 electric constant. 



In March 1960, Vul visited the United States to attend the 

 20th Annual Conference on Physical Electronics in Cambridge, 

 Massachusetts.
