Abstract

The ground state bands observed in even-even transfermium nuclei ²⁵⁰Fm and ^252,254No are investigated by the cranked shell model with the particle-number conserving treatment for the monopole and quadrupole pairing correlations. The experimental variations of the kinematic moment of inertia with rotational frequency are reproduced very well in our calculation. Our results show bankbendings of at ħω ≈ 0.275 and 0.300 MeV in ²⁵²No and ²⁵⁴No, respectively. The detailed information about the contribution to alignment from each cranked single particle level exhibits that the backbending is mainly due to the rapidly aligned angular momentum of proton 1j_15/2 [770]1/2 pairs and neutron 2h_11/2 [761]3/2, 1j_15/2 [734]9/2 pairs the band crossing.
