Abstract
Non-yrast levels of146Gd have been investigated by in-beamγ-ray and conversion electron spectroscopy following the144Sm(α, 2n) reaction at 25.7 MeV, an energy which was determined to provide optimum population of levels above the yrast line. The detailed146Gd level scheme includes twenty-one newly identified levels, many of which can be characterized in terms of specific proton particle-hole configurations. Several twoparticle-twohole states involving the 3− phonon have also been identified.
