THE FINE STRUCTURE IN THE FISSION YIELD CURVE FOR U$sup 23$$sup 3$

Measurements were made of the U/sup 233/ fission yield of Ba/sup 138/ Sr/ sup 88/ Sr/sup 90/ Y/sup 89/, and five isotopes of mzirconium. The yield of Cs/ sup 136/ and Rb/sup 86/ is estimated. The obtained data and previously published data are used for plotting graphs of the fission fragment yield. The graph shows the transition boundaries of light fragment, one neutron. and two neutron emisson. It is postulated that both structures are formed and related directly to the fission process moment.
