Abstract
Firm spin-parity assignments for the high-spin states up to 3.5 MeV in the one-proton nucleus147Tb were obtained from144Sm(6Li, 3n) in-beamγ-ray and conversion electron measurements. The energies of these two-particle one-hole excitations were calculated from the shell model with empirical nucleon-nucleon interaction energies. The calculated energy splittings agree well with experiment, whereas the theoretical excitation energies disagree by ≳1 MeV if recently measured ground state masses are used.
