General Comments:

2010Ga06: 69Co produced from inelastic scattering of secondary 64Cr beam at 87 MeV/nucleon on 9Be target using the S800 focal-plane detection at NSCL, MSU.

1991Be33 (also 1993BeZM): Identified from 239Pu(nthermal,f) with the recoil spectrometer LOHENGRIN. Measured T1/2 from time correlations between identified fragments and the β particles.

1994Se12: Produced by fragmentation of 58Cr beam on Th at E=800 MeV, followed by mass separation and tof isochronous spectrometer. Measured ground state mass.

Q-value: ΔS(p)=210 (syst,2021Wa16)

Q-value: S(2n)=11210 90, S(2p)=31380 220 (syst), Q(β-n)=5010 90 (2021Wa16)
