Description

Solving a coupled set of differential equations formed by a Fokker-Planck equation and a set of master equations, we can calculate the number of 'prefission' particles (n,p,a), which are emitted from a hot, rotating compound nucleus. Furthermore we get their energy spectrum and their angular momentum distribution. Our results depend sensitively on the friction parameter γ, the inertia M and the fission potential. Comparing the results with experimental data, we may learn something about these quantities. The investigations have been made for 187Ir and 185Os. (orig.)
