Structure ofAr39

Abstract
A spherical shell-model calculation of the odd- and even-parity states of Ar39 is made in a full sdpf model space. The calculation includes absolute binding energies and energy spectra, single-neutron spectroscopic factors, and electromagnetic and beta decay observables. Agreement with experiment is fairly good. Comparison is hampered by incomplete experimental knowledge and by the presence of low-lying intruder states.
