Description
High-spin states in the odd-proton nucleus 135Pm have been investigated using the 107Ag (32S, 2p2n)135Pm reaction. Seven rotational bands have been observed in 135Pm. The yrast band based on a decoupled h11/2 proton is found to have a band crossing in ωc ∼0.43 MeV/ℎ. Two positive-parity bands based on the two signature components of the πg7/25/2+[413] Nilsson orbital have been observed in the main sidebands. The favoured band with (π, α)(+ , -1/2) has been shown to populate below the first pair of proton alignment. Both bands have shown up bend at ω1 ∼0.26 MeV/ℎ and ω2∼0.43 MeV/ℎ. These crossing frequencies can be attributed to the decoupling of the first pair of h11/2 quasi-proton and h11/2 quasi-neutron, respectively. Four weaker bands have been observed in sidebands too. Among them, two states are possibly built on a πd5/23/2+[411] configuration
