Description of the odd ${}^{249-253}$No nuclei using Skyrme functionals with modified spin-spin interaction

Abstract

The Skyrme energy-density functionals with modified spin-spin interaction and pairing strength are used for description of the ${}^{249}$No, ${}^{251}$No, and ${}^{253}$No excited states. The results of the HFB and cranked HFB calculations taking into account the blocking effect are in reasonable agreement with the available data. For many states, including rotational and three-quasiparticle states, the results of self-consistent calculations were obtained for the first time.
