Description
The ground state and first excited 2+ state in proton-rich 36Ca have been studied at Ganil by gamma-ray spectroscopy of one-neutron knock-out reactions from deeply bound states in 37Ca at intermediate energy. The 2+ energy in 36Ca was found to be consistent with a sizeable N=16 gap similar to the Z=16 one observed in the mirror nucleus 36S. Partial cross-sections and momentum distributions of the knock-out reactions to both the ground state and the first excited 2+ state have been measured and the angular momentum of the two populated states identified. In contrast with previously reported cases, the extracted spectroscopic factors and their comparison to shell-model spectroscopic factors are found to be consistent with the trend observed for stable and near-magic nuclei.
