Calculation of Kinetic Energy and Most-Probable Charge in Fission

Abstract

Kinetic energies and most-probable charges in fission were calculated for ²³⁵U+n, ²⁵²Cf and ²²⁶Ra+p by applying the statistical model by Fong. The mass formula by Myers and Swiatecki was employed to evaluate fragment deformation energies. The most-probable scission configuration for a given mass division was obtained by maximizing the effective intrinsic excitation energy of the complementary fragments which was given as a function of their charges and deformation parameters. The general trends of the kinetic energy distribution and the charge distribution in fission could be reproduced fairly well.
