Abstract：
High-spin states of ¹⁶²Lu have been produced and studied via the ¹⁴⁷Sm ( ¹⁹F,4nγ) ¹⁶²Lu reaction. In-beam γ-rays were measured by using 1 planar detector and 7 high-purity Ge detector with BGO anti-Compton shield. The level scheme of the yrast band in ¹⁶²Lu was established for the first time and the signature inversion in energy was discovered at the low rotational frequencies. The yrast bands of doubly odd nuclei in the A=160 mass region have been reinvestigated and the systematics of signature inversion is briefly discussed.
