Spectroscopy ofSm145via (d, p) Reactions

Abstract

States of ${\mathrm{Sm}}^{145}$ have been investigated via 15-MeV-deuteron-induced ($d, p$) reactions with an energy resolution of ∼40 KeV. The angular-distribution data have been analyzed using zero-range distorted-wave Born-approximation calculations to extract spectroscopic information. The proton spectra do not show the simple structure that one would expect from the conventional shell model for an 82-neutron target nucleus. Spin and parity assignments for most of the observed levels together with single-particle energies are presented.
