Structure of the N=27 isotones derived from the 44Ar(d,p)45Ar reaction

The $^{44}\\mathrm{Ar}$($d,p$)$^{45}\\mathrm{Ar}$ neutron transfer reaction was performed at $10A$ MeV. Measured excitation energies, deduced angular momenta, and spectroscopic factors of the states populated in $^{45}\\mathrm{Ar}$ are reported. A satisfactory description of these properties is achieved in the shell model framework using a new $\\mathit{sdpf}$ interaction. The model analysis is extended to more exotic even-$Z$ nuclei down to ${}_{14}^{41}{\\mathrm{Si}}_{27}$ to study how collectivity impacts the low-lying structure of $N=27$ neutron-rich nuclei.
