General Comments:

2019Wi08: 68Br produced in fragmentation of secondary beams of 70Br, 70Kr, 71Kr, and 72Kr at 170 MeV/nucleon on 9Be targets. Secondary beams produced in fragmentation of 78Kr beam at 345 MeV/nucleon at RIKEN Nishina Center. Secondary beams analyzed with Bρ-ΔE-tof method using the BigRIPS separator. Reaction products following the secondary fragmentation analyzed with the ZeroDegree Spectrometer. First identification of 68Br. Deduced T1/2 estimate from comparison of measured to expected yields.
