Abstract

The level structures of146Gd and147Gd have been investigated by in-beamgamma-ray ande – spectroscopy with (agr, xn) reactions on enriched Sm targets. Detailed level schemes up to sim4 MeV, which differ radically from earlier schemes, are reported. The energy levels are characterized as particle-hole excitations using empirical single particle energies and two nucleon interactions. Analysis of pure 1p 1h proton excitations demonstrates that theZ=64 andN=82 energy gaps are about equally large.
