摘要：
Results from the gamma-ray spectroscopy of Ar-47,Ar-48 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 Ar-48.
