Abstract
High spin states of the odd-odd Lu-162 nucleus have been studied via S m-147(F-19,4n gamma)Lu-162 reaction at 95 MeV beam energy. Level schem e for yrast band based on pi[h(11/2)]nu[i(13/2)] quasiparticle configu ration was established up to I-pi=(23(-)) for the first time. This ban d shows the signature inversion in energy before backbending generally appeared in this mass region. It is stressed that the signature split ting in Lu-162 is larger than that in the Tm-160 nucleus.
