# Shell-model-like approach based on cranking covariant density functional theory: Band crossing and shape evolution in Fe 60

@article{Shi2018ShellmodellikeAB, title={Shell-model-like approach based on cranking covariant density functional theory: Band crossing and shape evolution in Fe 60}, author={Z. F. Shi and Z. Zhang and Q. B. Chen and S. Q. Zhang and Jie Meng}, journal={Physical Review C}, year={2018}, volume={97}, pages={034317} }

The shell-model-like approach is implemented to treat the cranking many-body Hamiltonian based on the covariant density functional theory including pairing correlations with exact particle number conservation. The self-consistency is achieved by iterating the single-particle occupation probabilities back to the densities and currents. As an example, the rotational structures observed in the neutron-rich nucleus $^{60}\mathrm{Fe}$ are investigated and analyzed. Without introducing any ad hoc…
