Charge/mass yields in the fission of highly excited heavy actinides

Abstract

The charge (mass) distributions of fission fragments resulting from low- and high-energy fission of the isotopes of Fm and No are studied with the statistical scission-point fission model. The calculated results are compared with the available experimental data. The transformation of the shape of the charge distribution with increasing isospin and excitation energy occurs gradually. At some critical excitation energy the the saturation of the symmetric component of the charge (mass) yield is demonstrated.
