Abstract

One-neutron knockout at intermediate beam energies, an experimental approach sensitive to the single-particle structure of exotic nuclei, has been applied to the well-bound N = 16 isotones ³⁴Ar, ³³Cl and ³²S as well as to the N = 14 nucleus ³²Ar where the knockout residue ³¹Ar is located at the proton drip line. The reduction of single-particle strength compared to USD shell-model calculations is discussed in the framework of correlation effects beyond the effective-interaction theory employed in the shell-model approach.
