Mass-separator measurements of mass and energy distributions for products of 235U fission by thermal neutrons

The mass separator measurements have been performed of the mass and energy distributions of heavy group nuclear products of 235U fission induced by thermal neutrons. For A=130-147 the relative yields have been determined at fixed energies Esub(l) of a supplementary light fragment. A higher yield for A=137 at certain Esub(l)s has been observed. The behaviour of the dependence of the mean kinetic energy and total kinetic energy of the heavy products on A exhibits periodical variations. The A dependence of the half width of the energy distribution for fission products of fixed mass also has some structural peculiarities
