Ground-state bands and excitation modes in [sup 183]Hg

A new in-beam study in [sup 183]Hg levels has been carried out by using the [sup 155]Gd([sup 32]S,4[ital n]) reaction at a beam energy of 160 MeV. A new pair of signature-partner bands, with large signature splitting, has been established in [sup 183]Hg. The band head of these signature-partner band...

Zusammenfassung:	A new in-beam study in [sup 183]Hg levels has been carried out by using the [sup 155]Gd([sup 32]S,4[ital n]) reaction at a beam energy of 160 MeV. A new pair of signature-partner bands, with large signature splitting, has been established in [sup 183]Hg. The band head of these signature-partner bands is assigned to be the ground state of [sup 183]Hg with a configuration of 1/2[sup [minus]][521]. The measured ratios of directional correlations (DCO ratios) revealed decay patterns for the proposed 9/2[sup +][624] bands in [sup 183]Hg different from those of [sup 185]Hg.
