Collective and broken pair states of 65, 67Ga
Excited states of 65Ga and 67Ga nuclei were populated through the 12C(58Ni, alpha p) and 12C(58Ni, 3p) reactions, respectively, and investigated by in-beam gamma-ray spectroscopic methods. The NORDBALL array equipped with a charged particle ball and 11 neutron detectors was used to detect the evaporated particles and gamma rays. The level schemes of 65, 67Ga were constructed on the basis of gamma gamma-coincidence relations up to 8.6 and 10 MeV excitation energy, and I pi = 27/2 and 33/2 + spin and parity, respectively. The structure of 65, 67Ga nuclei was described in the interacting boson-fermion plus broken pair model, including quasiproton, quasiproton-two-quasineutron and three-quasiproton fermion configurations in the boson-fermion basis states. MOst of the states were assigned to quasiparticle + phonon and three quasiparticle configurations on the basis of their electromagnetic decay properties.
