Effect of time-reversal symmetry breaking on static properties of rare-earth nuclei within Hartree-Fock-Plus-Bardeen-Cooper-Schrieffer approach

In the recent years, there has been an increase of studies on odd-mass nuclei at the mean-field calculations but there is lack of exploration on the rareearth nuclei. A study on global static properties of odd-mass rare-earth nuclei was carried out within Hartree-Fock-plus-Bardeen-Cooper-Schrieffer...
