Angular momentum and energy dependence of fission andn, p,4He emission from194Hg compound nucleus

Abstract

Spin and temperature dependence of the fission and particle emission is studied for 194Hg. The compound nucleus is described using the Strutinsky shell correction approach extended for finite angular momenta and temperature. The shell corrections to the potential energy, free energy and the angular momentum are calculated using the Woods-Saxon average field. Results are compared with the experimental data and show a good qualitative agreement. It is found that the inclusion of the shell effects is necessary to understand the decay properties of ~94Hg even for temperatures as high as 1.5 2.0 MeV.
