The distribution of the total kinetic energy of additional fragments as a function of their mass ratio is measured with a gas ionization chamber. The difference between the average kinetic energies in symmetrical fission and the fission in which the

The number of neutrons v emitted by fragments in the fission of U235 by thermal neutrons is measured with the aid of an ionization chamber and a neutron detector containing cadmium. The data thus obtained contradict the hypothesis of the universal de

A large detector filled with a liquid organic scintillator containing cadmium has been used to measure the number of neutrons emitted by individual fragments in U235 fission by thermal neutrons. Using 4 π geometry the dependence of the number of neu

The variation of νeff for the isotopes U233, U235 and Pu239 is measured in the superthermal region of neutron energies. For U233 νeff remains constant up to an energy of the order of 100 ev. For Pu239 νeff drops by 12% on going from the thermal sp

Measurements of η have been made with the dE/E spectrum, bounded at the lower end by 0·15 eV and 0·4 eV as a result of using gadolinium and cadmium filters respectively. The various Pu 239 specimens contained 0%, 1·6%, 2·5%, 6·5%, and 16% of Pu

Measurements are taken on νeff for the isotopes U233, U235 and Pu239 for neutrons with energies from 30 to 900 kev. It is discovered that in this energy region νeff increases substantially as the neutron energy increases.

The number of neutrons nu emitted by U/sup 234/ and Pu/sup 240/ is measured for different ratios of fragment masses. A sharp increase of nu is detected in the symmetrical fission region. The dependence of nu on the mass ratios correlates well with th
