Abstract：
The high-spin states in ¹⁸⁷Pt have been studied experimentally by means of in-beam γ-ray spectroscopy techniques via the ¹⁷³Yb(¹⁸O, 4n) fusion-evaporation reaction. The high-spin level scheme of ¹⁸⁷Pt has been established, including three rotational bands. Based on the systematics of level structure in neighboring nuclei and by comparing the experimental and theoretical B(M1)/B(E2) ratios, configurations of 11/2⁺[615], 7/2^－[503] and 1/2^－[521] have been proposed for the three rotational bands, respectively. Band properties of band crossing frequency, alignment gain and signature splitting have been discussed.
