ALIKHANOV, ABRAM ISAAKQVICH (Nuclear Physicist) 



A. L Alikhanov was born March 4, 1904. In 1931 he gradu- 

 ated from Leningrad Polytechnical Institute. He had been on 

 the staff of the Physico-Technical Institute of the U.S.S.R. 

 Academy of Sciences since 1927 and became the Director of its 

 Power Engineering Laboratories. In 1939 Alikhanov was elect- 

 ed a Corresponding Member of the U.S.S.R. Academy of Sciences 

 and in 1943 an Academician. He has also been a member of the 

 Armenian S.S.R. Academy of Sciences since 1943. In 1941 and 

 1948 he was a recipient of Stalin Prizes. 



The first scientific investigations of Alikhanov were in the 

 field of x-rays. In 1934 in collaboration with his brother, 

 Artemii Isaakovich Alikhan'yan, he began research in radio- 

 activity, and in the same year, jointly with M. S. Kozodaev and 

 Alikhan'yan, discovered the pair emission by excited nuclei. 

 In 1935, together with Alikhan'yan, he formulated the relation- 

 ship between j3- spectra and the atomic number of the element. 

 In 1936, with Alikhan'yan and L. A. Artsimovich, Alikhanov 

 proved experimentally the conservation of momentum during 

 pair annihilation. Investigations of cosmic rays (1939) led 

 Alikhanov, together with A. I. Alikhan'yan and S. Ya. Nikitin, to 

 the discovery of unstable mesons. In 1949, he built the first 

 reactor in the U.S.S.R., using heavy water as a moderator. At 

 present Alikhanov is working on the development of nuclear 

 reactors. 



As of 1961, Alikhanov was Director of the Institute of Theo- 

 retical and Experimental Physics and is Chairman of the Com- 

 mission on Cosmic Rays.
