Effects of Finite Ground-State Spin on Fission Fragment Angular Distributions Following Collisions with Spherical or Deformed Nuclei

Butt, Rachel D; Dasgupta, Mahananda; Gontchar, I.I.; Mukherjee, A.; Berriman, Annette; Morton, Clyde; Newton, John; Stuchbery, Andrew; Lestone, J; Hinde, David


The influence of the ground-state spin of fusing nuclei on the subsequent fission fragment angular distributions has been investigated through realistic quantum-mechanical calculations. The domain of applicability of an approximate formula is found for spherical nuclei. For deformed nuclei, a generalization of the standard transition state model expression for the fission fragment angular distribution is presented. This predicts dramatic changes in the shape and anisotropy of the distribution,...[Show more]
