Abstract

The energy levels of 182Hg have been identified for the first time through comparison of in-beam studies of the reactions 156,154Gd(32S, 4n)184,182Hg and γ-X-ray coincidences. Levels up to 12+ in 182Hg were established from γ-γ coincidences and singles measurements. The data establish that the ground state shape is near spherical, and that the ground band is crossed by a well-deformed band at 4+. In contrast to IBA model predictions that the deformed band will rise in energy in 182Hg compared to 184Hg, the energies of the deformed levels in 182Hg continue to drop. © 1984.
