Abstract

Using a148Gd radioactive target and the (p,d), (d,t), and (3He,α) single neutron pick-up reactions we have measured the147Gd mass excess as — 75,366(4) keV, which differs by 139(24) keV from the adopted value of the 1983 mass table. From this result, and from recently reported first transfer-reaction mass determinations for145Eu and146Eu, we have recalculated the masses of nuclei above146Gd from a previous shell model analysis of high-spin states.
