ALEKSANDROV 4 



of Physical Problems of the U.S.S.R. Academy of Sciences. 

 Aleksandrov was a participant at the two Geneva Conferences 

 of the United Nations on Peaceful Uses of Atomic Energy in 

 1955 and 1958. In 1959 he visited the United States with the 

 Soviet delegation of atomic energy experts. After I. V. Kurcha- 

 tov's death (nuclear physicist, 1902-1960), Aleksandrov was 

 named his successor as Director of the Kurchatov Institute. 

 Aleksandrov became a Corresponding Member of the U.S.S.R. 

 Academy of Sciences in 1943 and in 1953 an Academician. He 

 is the recipient of a Stalin Prize. 



Aleksandrov' s scientific work deals with the physical nature 

 of insulators and investigations of mechanical and electrical 

 properties of high-polymers. He studied the properties of 

 polymerized styrene, developed methods of its polymerization 

 and constructed condensates from polystyrene. Aleksandrov 

 also investigated the mechanical properties of other polymers 

 and amorphous substances; he proposed a static theory of sta- 

 bility of solids. He developed a relaxation theory of elasticity, 

 studied the solidification of polymers and the nature of phase 

 transitions. He was also active in the development of nuclear 

 reactors in the post World War II period. 



As of 1961, Aleksandrov was a Member of the Presidium of 

 the U.S.S.R. Academy of Sciences. He was elected as a dele- 

 gate from R.S.F.S.R. to the Supreme Soviet on March 18, 1962.
