Abstract
The level schemes of the neutron-rich isotopes are investigated via in-beam -ray spectroscopy following the fragmentation of a projectile beam at intermediate beam energies. Information on coincidence relationships complemented by comparisons to shell-model calculations in the model space were used to construct excitation level schemes for these neutron-rich nuclei. For the odd-mass isotopes, a level scheme is presented that appears essentially complete at low energies and exhausts the states predicted by the SDPF-MU shell-model Hamiltonian. Simple Nilsson configurations are proposed for the low-lying excited states of from an analysis of the transition matrix elements and moments calculated within the shell model.
