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