Identification of 183hg. Identical Bands in 183,185Hg

In-beam γ-ray transitions in 183Hg have been identified from fragment-γ and γ-γ coincidence measurements using the Argonne Fragment Mass Analyzer (FMA). The γ-ray transitions in 183Hg were placed into five bands. Two of these have been associated with the [624]92+ orbital and exhibit signature splitting, as expected for i132 excitations built on a prolate shape moderate deformation. Two other bands which do not show signature splitting have been associated with the [514]72− orbital and exhibit transition energies "identical" to the bands with the same configuration in 185Hg.
