Band structures in neutron-rich $A \sim 60-80$ nuclei via deep-inelastic reactions with Gammasphere*

Several experiments have been performed at Argonne National Laboratory in the past few years using deep-inelastic reactions on thick $^{238}$U targets to produce neutron-rich nuclei in the $A \sim$ 60 to 80 mass region. Beams of 430-MeV $^{64}$Ni, 530-MeV $^{76}$Ge, and 630-MeV $^{82}$Se have been provided by the ATLAS facility at ANL. Gamma rays were detected with the Gammasphere Ge-detector array. Band structures have been newly observed in a number of neutron-rich nuclei [e.g., I. Stefanescu {\it et al.}, Phys. Rev. C {\bf 79}, 064302 (2009)]. In some cases, spin and parity assignments are strengthened by angular-correlation measurements. These observations can provide insights into the single-particle and collective properties of these nuclei. Highlights of this study will be presented.
