Abstract : High spin states of the odd-odd l62 Lu nucleus have been studied via 147 Sm(19 F,4nγ) reaction at 95MeV beam energy. Level scheme for yrast band based on π [ h11/2 ]v [i13/2 ] quasiparticle configuration was established up to Iπ = (23- ) for the first time. This band shows the signature inversion in energy before backbending generally appeared in this mass region. It is stressed that the signature splitting in 162 Lu is larger than that in 160 Tm nucleus.
