One-neutron knockout from ${}^{57}$Ni

Abstract

The single-particle structure of ${}^{57}$Ni and level structure of ${}^{56}$Ni were investigated with the \mbox{${}^9$Be (${}^{57}$Ni,${}^{56}$Ni+$\gamma$)$X$} reaction at 73 MeV/nucleon. An inclusive cross section of 41.4(12) mb was obtained for the reaction, compared to a theoretical prediction of 85.4 mb, hence only 48(2)% of the theoretical cross section is exhausted. This reduction in the observed spectroscopic strength is consistent with that found for lighter well-bound nuclei. One-neutron removal spectroscopic factors of 0.58(11) to the ground state and 3.7(2) to all excited states of ${}^{56}$Ni were deduced.
