β-delayed γ-ray spectroscopy of ^196Hg and its description within the extended supersymmetry
Abstract
The concept of nuclear structure SUSY has been observed and investigated in the Au-Pt mass region. It allows the simultaneous description of different nuclei forming so-called supermultiplets. All members of a supermultiplet are distinguished by a constant number of IBFM ν- and π-bosons and -fermions. The most popular example is the `magic square' consisting of ^194,195Pt and ^195,196Au. Recently, efforts were made to investigate the expansion of the Au-Pt supermultiplets by a fifth member: the neighboring even-even Hg isotopes. For the square around ^194Pt, this corresponds the 2-fermion--5-boson supermultiplet member ^196Hg. We report on a γγ angular-correlation experiment to complete the data on low-spin states in ^196Hg. It was performed at WSNL of Yale University using a 28-MeV proton beam activating an enriched ^198HgS target. The γ-rays following the decay of the β-unstable ^196Tl were observed off-beam with the YRAST-Ball Clover array. We present our results and discuss the description of ^196Hg within the extended supersymmetry model.
