摘要
The nucleus Ar-37 has been studied with gamma-ray spectroscopy in the Mg-24(O-16,2pn) reaction at a beam energy of 70 MeV. Twenty two new excited states up to an excitation energy of 13 MeV have been observed. We compare the first negative and positive parity yrast states with large-scale-shell-model calculations using the Antoine code and the SDPF interaction, considering the excitation of the 1d(5/2), 2s(1/2) and 1d(3/2) nucleons to 1f(7/2) and 2p(3/2) in the sdpf valence space.
