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.
