Low-lying spin states of even–odd 191Pt nucleus

Although the complex odd mass 191Pt nucleus has been studied theoretically by several models, there is still a lack of information concerning its electromagnetic moments and transitions. The present result of an interacting boson–fermion model-1 (IBFM-1) single and multilevel calculation for positive and negative parity states of the odd mass 191Pt nucleus are compared with experimental data, confirming the spin assignments for many low-lying energy states. Different core nucleus and levels have been used in this study. Electromagnetic moments based on the IBFM analysis are reported for the first time, as well as the multipolarity of transitions and mixing ratios. The present IBFM results show good agreement with the available experimental data.
