Statistical Model Analysis of Spin Influence on the Deexcitation of Fission Fragments

Neutrons and prompt gamma rays emitted by excited fission fragments have been studied using an angular momentum dependent statistical model. The computer program MAMI written for this purpose is described briefly. The difficulties in choosing suitable emission strengths are discussed in more detail. Some results are given, related to the influence of spin on competition between neutron and gamma-ray emission, on total average gamma-ray energy, on average neutron multiplicity, and on average neutron kinetic energy.
