Shape effects, U(3) symmetry and heavy clusterization

摘要

The structural aspects of the fission channels of ~(252)Cf are studied from the microscopic viewpoint using the U(3) selection rule. Effective U(3) symmetry labels, which are consistent with deformation, are used to characterize the parent and daughter nuclei. Our study shows a non-uniform structural dependence of the relative preference for different fission channels.
