Fission fragment angular distributions for the system 19F+232Th.

Abstract

The fission fragment angular distributions for the system $^{19}\mathrm{F}$${+}^{232}$Th have been measured at several bombarding energies between 94 and 108 MeV. Even though the anisotropy values measured in the present work are considerably smaller than the ones reported by Zhang et al. for the same system at similar energies, they are still anomalous when compared with the predictions of the standard saddle-point statistical model and fit into the systematics of entrance-channel dependence of fission anisotropies reported by us earlier.
