Abstract

Magnetic-dipole and electric-quadrupole moments for Ga65,67,69,75,79-82 are reported using the Collinear Resonance Ionization Spectroscopy (CRIS) technique at the ISOLDE facility, CERN. The moments of Ga65 have been measured for the first time: μ=+1.775(3)μN and Qs=+21.0(15)efm2. These results are compared to shell-model calculations using the GXPF1 and JUN45 interactions and the trends of the moments approaching the region of the doubly magic Ni56 are discussed. Additionally, new values for the change in mean-square charge radii for Ga65 and Ga67 allow investigation into the odd-even staggering in the region below N=40.
