文摘High spin states of the odd-odd ^(162)Lu nucleus have been studied via ^(147)Sm(^(19)F,4nγ)reaction at 95MeV beam energy.Level scheme for yrast band based on π[h_(11/2)]v[i_(13/2)]quasiparticle configuration was established up to I^(π)-(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 162Lu is larger than that in 160 Tm nucleus.
