High-spin level structure in the stable nucleus ¹⁹⁵Pt

The incomplete fusion reaction ¹⁹²Os(⁷Li, (p, d, t) xn) has been used to populate high-spin states in the heavy stable nucleus ¹⁹⁵Pt at a beam energy of 44 MeV. Based on the γ-γ coincidence relationships, relative intensities and ADO ratios, a level scheme consisting of 11 new γ transitions and 9 new levels is established for ¹⁹⁵Pt. In comparison with the level structures observed in neighboring nuclei, the vi_13/2^-1 and vi_13/2^-2 vj^-1(j=p_3/2, f_5/2) configurations have been proposed to the 13/2⁺ and 21/2^- states, and the properties of rotational band built on these states have been discussed with the help of Total-Routhian-Surface (TRS) calculations.
