Collinear laser spectroscopy was performed on the {sup 80}Ga isotope at ISOLDE, CERN. A low-lying isomeric state with a half-life much greater than 200 ms was discovered. The nuclear spins and moments of the ground and isomeric states and the isomer shift are discussed. Probable spins and parities are assigned to both long-lived states (3{sup -} and 6{sup -}) deduced from a comparison of the measured moments to shell-model calculations.
