Light particle emission in the reaction {sup 144}Sm({sup 32}S,fission) at E{sub lab}=838 MeV

Abstract

Energy spectra of light charged particles have been measured in coincidence with fission-like fragments using the 4{pi} charged-particle detector AMPHORA. Pre-equilibrium, pre-scission and post-scission components of emitted protons, deuterons, and alphas have been extracted from the energy spectra using a multiple source fit procedure. The results have been confronted with statistical model computations. A fair overall agreement is observed for different parameterizations of the Fermi gas level density parameter with indications for a decrease of the level density with increasing nuclear temperature. The correlations between slope parameter, pre-scission and total particle multiplicity turned out to be a sensitive probe for the level density parameter. (K.A.) 28 refs.; 12 figs.; 3 tabs.
