Laser spectroscopy was performed on the {sup 72,74,76,78}Ga isotopes at On-Line Isotope Mass Separator (ISOLDE) facility, CERN. Ground-state nuclear spins and moments were extracted from the measured hyperfine spectra. The results are compared to shell-model calculations, which provide a detailed probe of the nuclear wave function. The spin is established from the shape of the hyperfine structure and the parity inferred from a comparison of shell-model calculations with the measured nuclear moments. The ground states of {sup 76,78}Ga are both assigned a spin and parity of I{sup {pi}=}2{sup -}, while {sup 74}Ga is tentatively assigned as I{sup {pi}=}3{sup -}. For {sup 72}Ga, the results are consistent with the previous I=3 assignment.
