2010So03: 170Er(82Se,x), E=460 MeV; measured yields and distributions of product nuclei using PRISMA spectrometer, CLARA HPGe array of 23 Compton suppressed clover detectors. Deduced yields for the beamlike fragments relative to 84Kr and the corresponding target-like fragments as obtained from PRISMA in coincidence with CLARA.
Mass excess: -55523.1 keV 57 (2024Ja12) cf. -55600 keV 300 (2021Wa16)
