The energy spectrum and electromagnetic transition properties of the supermultiplet members with two proton fermions can be constructed using the dynamical U{sub v}(6/12) x U{sub {pi}}(6/4) extended supersymmetry. In order to investigate predictions of the two proton fermion--four neutron boson supermultiplet member {sup 198}Hg, an experiment with the HORUS cube {gamma}-ray spectrometer at the Cologne TANDEM accelerator was performed using the {sup 196}Pt({alpha},2n){sup 198}Hg reaction. By analyzing {gamma}{gamma} coincidence spectra and {gamma}{gamma} angular correlations, the required experimental data--level and decay energies, level spins and multipole mixing ratios--could be obtained. For the low-energy states, the experimental data show good agreement with theory.
