The effect of the angular momentum dependence of the fission probability on the determination of fission time scales from fission excitation functions

Abstract

The effect of the strong angular momentum dependence of the fission probability is shown to prevent a direct determination of the pre-saddle fission delay time from fission excitation functions. Neglect of this effect in the analysis of excitation functions causes an apparent drop in fission probability with excitation energy, which can be misinterpreted as evidence for a pre-saddled delay time. 20 refs., 3 figs.
