Dzhelepov, Venedikt Petrovich (born 12.04.1913) is a Soviet physicist and a corresponding member of the USSR Academy of Sciences (1966). Born in Moscow. Graduated from the Leningrad Polytechnic Institute (1937). In 1941–43 he worked at the Leningrad Physico-Technical Institute, in 1943–48 at the Kurchatov Institute of Atomic Energy, and in 1948–56 was deputy director of the Institute of Nuclear Problems of the USSR Academy of Sciences (Dubna). From 1956 he has been director of the Laboratory of Nuclear Problems of the Joint Institute for Nuclear Research (Dubna).
His research concerned nuclear physics, the physics of elementary particles, and the physics and engineering of accelerators. He took part in building and improving the first Soviet synchrocyclotron at Dubna. He carried out a series of studies of the elastic scattering of neutrons by neutrons which made it possible to prove the symmetry of nuclear forces at high energies. He was the first to study the spin dependence of the exchange forces in the neutron–proton system. Studying the production of pions in nucleon collisions, he confirmed the charge independence of nuclear forces. He detected the electron decay of negative pions in flight and studied the capture of negative muons in gaseous hydrogen. He determined the probabilities of these processes, which was of great importance in confirming the universality of the weak interaction. He discovered a number of new muon-catalysis reactions. He found that the probability of the formation of mesomolecules of the heavy isotopes of hydrogen has a resonance dependence. He carried out a broad series of studies of pion–nucleon interactions at high energies. He was one of the leaders of the work that produced the world's first accelerator with a spiral variation of the magnetic field, and also the electron model of a relativistic cyclotron with strong focusing, on which it was shown that accelerated proton currents of hundreds of milliamperes can be obtained in such cyclotrons at energies of the order of 700–1000 MeV. He also works on the application of nuclear physics in medicine.
USSR State Prizes (1951, 1953).
