Abstract

Results from the $γ$ -ray spectroscopy of ${}^{47, 48}{Ar}$ exemplifying new limits of sensitivity for characterizing neutron-rich nuclei at energies around the Coulomb barrier are presented. The present results, along with interacting shell model calculations, highlight the role of cross-shell excitations and indicate the presence of a nonaxial deformation in ${}^{48}{Ar}$ .
