Influence of Zero-Point Vibrations on Multipole Moments of Rare Earth Nuclei

摘要

The influence of the zero-point quadrupole-hexadecapole vibrations on multipole moments and mean square radii for rare earth nuclei was investigated. The Born-Oppenheimer approximation was used to separate collective and intrinsic motion. The macroscopic-microscopic method in the potential energy part and cranking model in the kinetic energy part was used to construct the collective Hamiltonian. The intrinsic motion was described in terms of Nilsson single-particle potential and BCS theory. Systematic improvement to static calculations was achieved. (ERA citation 11:028907)
