Abstract

The (3He,d) and (t, α) reactions on a radioactive Z=64148Gd target were used to populate the single-proton states in149Tb and147Eu. In149Tb the data establish the five single-proton states of the 51 to 82 major shell. The proton occupancies deduced from these experiments suggest that in the148Gd ground state there are on average 1.8(3) proton pairs above the Z=64 shell gap.
