The general goal of this work has been to apply and develop theoretical models for the low energy structure of atomic nuclei. A major focus in recent years has been the theoretical description of proton emission from spherical and near-spherical nuclei. Another broad area involves phenomenological particle-core coupling, in which one or a few particles are explicitly coupled to a collective core. Level energies, spins, parities, and electromagnetic matrix elements (both static moments and transition rates) can be calculated and compared with experimental data, for both low-spin and high-spin states. Such calculations can be used to probe the collective core (e.g., ''the nuclear shape''), identify and characterize particular deformed single-particle orbitals (Nilsson states) and investigate residual interactions between unpaired nucleons (e.g., proton-neutron interactions in odd-odd nuclei). A complete list of collaborators is given.
