Abstract：
High-spin states in ¹⁶²Lu have been roduced and studied via ¹⁴⁷Sm (¹⁹F, 4nγ) ¹⁶²Lu reaction. lh-beam γ-rays were measured by using 1 planar detector and 7 high purity Ge detectors 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 for The yrast bands of doubly odd nuclei around A=160 mass region have been reinvestegated and the systematics of signature inversinon was discussed briefly.
