Abstract

The Bohr Hamiltonian prescription for collective behavior in heavy nuclei is used with the ground state, vibrational and rotational bands each allowed unique mass parameter values. Excited-state energies and E2 transition probabilities of the nuclei ^{163, 165}Er are calculated, these nuclei being selected for their particular relevance to the model, and their topical nature in both theoretical and experimental studies.
