Prompt Fission Neutrons as Probes to Nuclear Configurations at Scission

摘要

Prompt fission neutrons and gamma-rays emitted by excited primary fission fragments are indirect probes to the nuclear configurations present near the scission point. By studying detailed characteristics of these quantities, it is shown that one can discriminate between various assumptions regarding the sharing of the free energy at scission among the two fragments. The case of low-energy neutron-induced fission on 235U is studied and interpreted in terms of fission modes.
