Neutron spectroscopic factors of ${}^{55}$Ni hole-states from (p,d) transfer reactions

Abstract

Spectroscopic information has been extracted on the hole-states of ${}^{55}$Ni, the least known of the quartet of nuclei (${}^{55}$Ni, ${}^{57}$Ni, ${}^{55}$Co and ${}^{57}$Co), one neutron away from ${}^{56}$Ni, the N=Z=28 double magic nucleus. Using the ${}^1$H(${}^{56}$Ni,d)${}^{55}$Ni transfer reaction in inverse kinematics, neutron spectroscopic factors, spins and parities have been extracted for the f${}_{7/2}$, p${}_{3/2}$ and the s${}_{1/2}$ hole-states of ${}^{55}$Ni. This new data provides a benchmark for large basis calculations that include nucleonic orbits in both the sd and pf shells. State of the art calculations have been performed to describe the excitation energies and spectroscopic factors of the s${}_{1/2}$ hole-state below Fermi energy.
