Abstract

The level schemes of the neutron-rich P3742 isotopes are investigated via in-beam γ-ray spectroscopy following the fragmentation of a Cl45 projectile beam at intermediate beam energies. Information on γγ coincidence relationships complemented by comparisons to shell-model calculations in the sdpf model space were used to construct excitation level schemes for these neutron-rich nuclei. For the odd-mass P37,39 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 P38,39,40,41 from an analysis of the E2 transition matrix elements and moments calculated within the shell model.
