Evolution of the Position of Single-particle Levels in Neutron-rich Cerium and Neodymium Isotopes
Résumé
Different Skyrme functional parametrizations were tested for Ce and Nd isotopes for N > 82. The method employed in the study is the axial Skyrme–Hartree–Fock model+BCS. For selected parametrizations, ground-state deformations β2,β3 and β4 have been found and the evolution of single-neutron and single-proton states around the Fermi level along the chain of Ce and Nd isotopes has been investigated. These results were then compared to the existing experimental data.
