Abstract

Neutron pick-up measurements have identified the s12 and d32 holes states in 147Gd, 145Sm, and 143Nd. The results also locate the 12+ and 32+ members of the vf72×3 septuplet via their admixtures from these hole states. Additional energy perturbations of the septuplet result largely from a negative quadrupole moment of the octupole phonon, with a Z-dependence consistent with the microscopic structure of the 3 excitation in the N=82 nuclei.
