Configuration and bandhead spin assignments for the 2-quasiparticle rotational bands in the neutron-rich nuclei ${}^{154,156}$Pm

Shuo-Yi Liu, Miao Huang, Zhen-Hua Zhang

The rotational bands in the neutron-rich nuclei ${}^{153-157}$Pm are investigated by a particle-number conserving method. The kinematic moments of inertia for the 1-quasiparticle ban…
