Abstract

High-spin states in ¹⁸⁵Pt have been investigated using the ¹⁷³Yb(¹⁶O, 4n) reaction at a beam energy of 90 MeV. The 7/2^-[503] band in ¹⁸⁵Pt is revised, and particularly the intra-band B(M1)/B(E2) ratios are deduced experimentally. Low-spin signature inversion is revealed in the 7/2^-[503] band. The signature inversion can be interpreted if we assume configuration change in this band from the 7/2^-[503] orbital to the 7/2^-[514] orbital with increasing spin, which is supported by comparing the measured B(M1)/B(E2) ratios with the theoretical values from the semi-classical Dönau and Frauendorf approach.
