Fission time scales from prescission charged particle multiplicities

Abstract

Pre-scission charged particle multiplicities, following fusion of {sup 164,167,170}Er + {sup 28}Si, have been measured. The multiplicities at the lowest bombarding energies limit the statistical model level density parameters. More importantly the {alpha}-data restrict the time spend near equilibrium and suggest evaporation occurs predominantly from larger deformations. 18 refs., 6 figs.
