General Comments:

2010Oh02: 76Co nuclide identified in Be(238U,F) and Pb(238U,F) reactions with a 238U86+ beam energy of 345 MeV/nucleon produced by the cascade operation of the RBIF accelerator complex of the linear accelerator RILAC and four cyclotrons RRC, fRC, IRC and SRC. Identification of 76Co nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss of the fragments using BigRIPS fragment separator. Experiments performed at RIKEN facility. Based on α/Q spectrum and Z versus α/Q plot, 5 counts were assigned to 76Co isotope. (Q=charge state)

2014Xu07: 76Co nuclide produced in 9Be(238U,F) reaction with a 238U86+ beam of 345 MeV/nucleon produced by the RIKEN accelerator complex. Separation of 76Co nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss of the fragments (ΔE-Bρ-tof method) using BigRIPS fragment separator and and ZeroDegree Spectrometer (ZDS) at RIBF-RIKEN facility. Based on α/Q spectrum and Z versus α/Q plot. Measured heavy fragment, β and γ spectra using wide-range active silicon strip stopper array (WAS3ABi) for β and ion detection, and EUROBALL-RIKEN Cluster array for γ detection. Decay curves were obtained from time differences between implantation and correlated β decays

2000Is13: calculated S(n), S(2n), Q(β-)

Q-value: Q(β-) and S(n) from 2012Wa38; S(p) and Q(α) from 1997Mo25

Q-value: Estimated uncertainties (2012Wa38): 950 for Q(β-), 1060 for S(n)

Q-value: S(2n)=7780 1000, Q(β-n)=12080 860 (syst,2012Wa38). S(2p)=39380 (1997Mo25,calculated)
