The neutron rich odd mass Gallium isotopes have recently received much attention as they were examined by various experimental techniques with the aim of systematically studying the nuclear structure from the spin and parity of the ground state (gs) and excited states (see for example [1]). From collinear laser spectroscopy experiments conducted at ISOLDE, an increased occupancy of the proton f5/2 level was observed starting from N=42 onwards and leading to shape changes as well as an unexpected collective ground state with spin I=1/2 for 73Ga and I=5/2 for 81Ga [2]. This reordering of the proton f5/2 and p3/2 orbits as the neutron g9/2 orbital is being filled, was previously observed in the Cu isotopes to occur in 75Cu with a gs dominated by a proton in f5/2 [3].
In this submission we will present the systematics of neutron rich odd-odd Ga isotopes from 72Ga to 80Ga. Currently known spectroscopic information and recent spin and moment measurements allow us to study the effect of the odd g9/2 neutron coupling to an odd number of protons in the f5/2 or p3/2 orbits.
