Abstract：
High spin states of odd-odd nucleus ¹⁵⁸Tm have been studied by using ¹⁴⁴Nd( ¹⁹F,5n) reaction at beam energies of 108 and 112MeV. Two new bands are identified. And their possible configurations and spin/parity assignments are discussed. Furthermore, experimental B(M1)/B(E2) values are obtained for the πh _11/2⊙νi _13/2band and compared with calculations based on geometric model.
