Ground State Shape and Crossing of Near Spherical and Deformed Bands in exp 182 Hg

摘要

The energy levels of exp 182 Hg have been identified for the first time through comparison of in-beam studies of the reactions exp 156 exp 154 Gd( exp 32 S,4n) exp 184 exp 182 Hg. Levels up to 12 exp + in exp 182 Hg were established from gamma - gamma coincidence and singles measurement. 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 exp + . In contrast to IBA model predictions that the deformed band will rise in energy in exp 182 Hg compared to exp 184 Hg, the energies of the deformed levels in exp 182 Hg continue to drop. 7 references.
