Ground-state bands and excitation modes inHg183

Abstract

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

Decay of 185Tl, 185m+gHg, 189m+gPb and energy location of the 13/2+ isomeric states in 185Hg, 189Pb, 193Po and 197Rn

“…This more precise value is in agreement within the error bars with our value and will be adopted later on (see fig. 9 [69] and at 286 keV [68] in 183 Hg, in fig. 10 we have adopted the data from [69] for the 1/2 − [521] band since three interband transitions supported their results.…”
