Abstract
In order to estimate the deformation rate of fission fragment at the scissi on point for thermal neutron-induced fission of U-233,U-235 and Pu-239, dou ble-velocity and double-energy measurements were carried out. As the result of the estimation of the deformation rate, two types of scission point con figurations were found. One type is composed of deformed light and heavy fr agments, and the other type is a combination of deformed light and spherica l heavy fragments. Mass and total kinetic energy distributions were sorted in two distributions by means of the type of configuration.
