High-spin states in doubly odd Ho-158

High-spin states in Ho-158 have been studied through the Sm-152(B-11,5n)Ho- 158 reaction at a beam energy of 60 MeV. In addition to the previously know n yrast band, three new rotational bands, namely, the {p7/2(-)[523] xn3/2(- )[521]}K-pi = 5(+) ground-state band, the {p7/2(+)[404]xn3/2(+)[651]}K-pi = 5(+) band, and the {p7/2(-)[523]xn 11/2(-)[505]}K-pi = 9(+) band, are prop osed. The yrast band is connected to the ground-state band, and its configu ration is reassigned as the {p7/2(-)[523]xn3/2(+)[651]}K-pi = 5(-) rather t han the {p7/2(-)[523]xn5/2(+)[642]}K-pi = 6(-). On the basis of the present experimental study, the spin values of the member states of the yrast band turn out to be larger by three units with respect to the earlier tentative spin assignments and in agreement with the latest spin assignments based o n the arguments of the level energy systematics and the alignment additivit y.
