| Bemærkning | Il’ja Mikhailovich Frank (1908 -1990) attended the Moscow State University as a pupil of Vavilov, and graduated in 1930.
In 1931 he became a senior scientific officer in Professor A.N. Terenin’s laboratory in the State Optical Institute in Leningrad, and in 1934 he joined the P.N. Lebedev Institute of Physics of the U.S.S.R. Academy of Sciences as a scientific officer. He was promoted firstly to senior scientific officer and, in 1941, to officer in charge of the Atomic Nucleus Laboratory. After 1957 he simultaneously occupied the post of Director of the Neutron Laboratory of the Joint Institute of Nuclear Investigations. The first investigations of I.M. Frank were in the field of photoluminescence and in photochemistry. From 1934 he worked on nuclear physics in the Laboratory of Professor D.V. Skobeltzyn. The experimental investigations of pair creation by g-rays and other problems connected with the measurements and application of g-rays were carried out by him. His further works were devoted to neutron physics, the investigation of reactions on light nuclei and nuclear fission by mesons. The subject of his theoretical investigations was the Vavilov-Cerenkov effect and related problems. Frank was awarded the degree of Doctor of Physico-Mathematical Sciences in 1935; in 1944 he was confirmed in the academic rank of Professor, and was elected a Corresponding Member of the U.S.S.R. Academy of Sciences in 1946. He won the Nobel Prize for Physics in 1952. Yakov Abraham Smorodinsky studied physics at the Lenigrad State University. He become the Ph.D. student of Lev Landau. In 1956 he became the Head of the Theoretical Group at the Laboratory of Theoretical Physics (now Bogoliubov Laboratory of Theoretical Physics), Joint Institute for Nuclear Research, Dubna. The Joint Institute for Nuclear Research was established on the basis of an agreement signed on March 26, 1956, in Moscow by representatives of the governments of the eleven founding countries, with a view to combining their scientific and material potential. |
