Excited states of the odd-odd nucleus 158Tb have been studied via the 154Sm(7Li ,3n) 158Tb reaction at a beam energy of 27 MeV. The new level scheme of 158Tb involving a positive parity rotational band is established up to excitation energy ∼2.3 MeV and spin ∼17ħ. By comparing with the rotational bands in the neighboring nuclei 157Tb and 157Gd, the configuration was tentatively assigned as πd5/2⊗ vi13/2 , and the phenomenon of signature inversion is discussed.
