Abstract
One-neutron knockout reactions from the deeply bound isotones with and 18 have been studied in inverse kinematics with intermediate-energy beams. -ray spectroscopy in coincidence with the detection of knockout residues allowed for an investigation of the one-neutron removal leading to individual excited states. Spectroscopic factors are deduced in the framework of the sudden and eikonal approximations and are compared to USD shell-model predictions. The momentum distributions observed in the experiment are used to identify the angular momentum carried by the knockedout neutron by comparing with calculations based on a black-disk reaction model. The systematics of reduced single-particle occupancies attributed to the effect of short-range correlations, observed so far for stable and near-magic nuclei in and reactions and in one-nucleon knockout on light deeply bound systems, are extended in this work.
