1974Gr29: production and identification of 80Ga from fission. Later studies: 1976Ru01, 1981Gi17, 1991Kr15, 1993Ru01. Isomerism in 80Ga discovered by 2010Ch50 and 2013Ve03.
2010Ch50: source of 80Ga produced by irradiation of uranium carbide target with a proton beam at ISOLDE, CERN facility. Collinear laser spectroscopic techniques used on the extracted 30-keV mass separated ion beam. Selective Ga yield was provided by resonance ionization laser ion source (RILIS). Measured hyperfine structure, deduced spins, magnetic moments and quadrupole moments. Known moments for 71Ga were used for calibration. See also 2012Pr11 and 2011Ma45 for hyperfine structure measurements and rms charge radii.
2013Ve03: 80Ga isotope produced in electrofission of uranium. Target of UCx was bombarded by 50-MeV electron primary beam followed by mass separation using PARRNe mass separator installed on-line to the ALTOISOL facility at IPN-Orsay. Measured Eγ, Iγ, β events using an HPGe detector from Phase 1 type EUROGAM, and a small EXOGAM Clover Ge detector. Measured half-lives from the decay curves of 67 γ rays. Evidence for a second long-lived activity in 80Ga
