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] 9 2 + orbital and exhibit signature splitting, as expected for i 13 2 excitations built on a prolate shape moderate deformation. Two other bands which do not show signature splitting have been associated with the [514] 7 2 − orbital and exhibit transition energies “identical” to the bands with the same configuration in 185Hg.
