Rotational properties of the superheavy nucleus $^{256}$Rf in
particle-number conserving cranked shell model
   [PDF]

Zhen-Hua Zhang, Jie Meng, En-Guang Zhao, Shan-Gui Zhou
The kinematic and dynamic moments of inertia of the ground state band in the recently observed nucleus $^{256}$Rf and some neighboring even-even nuclei are investigated by using a cranked shell model (CSM) with the pairing correlations treated by a particle-number conserving (PNC) method, in which the blocking effects are taken into account exactly. The determined spin of the observed ground state band in $^{256}$Rf by comparing the kinematic moments of inertia with the calculations of the PNC-CSM agrees with previous spin assignment. The effects of the high order deformation $\varepsilon_6$ on the delayed alignment in $^{254}$No relative to $^{256}$Rf as well as on dynamic moment of inertia are discussed.
