Structures of odd mass transfermium nuclei by a particle-number conserving cranked shell model

The cranked-shell model (CSM) with pairing correlations treated by a particle-number conserving (PNC) method is used to study the rotational properties of odd mass transfermium nuclei. In the PNC method, the particle number is conserved and the Pauli blocking effects are taken into account exactly. By fitting the experimental single-particle spectra in these nuclei, a new set of Nilsson parameters (κ and μ) are proposed. The experimental kinematic moments of inertia in these transfermium nuclei are reproduced quite well by the PNC-CSM calculations. The structures of the single-particle states, deformation, high-j intruder orbital and the rotational properties in these nuclei are investigated in detail.
