Low-Energy Spectra of Nobelium Isotopes / M.Mardyban, V.Nesterenko // The 2nd International African Symposium on Exotic Nuclei IASEN2024, Cape Town, 09 - 13 December 2024 : Book of Abstracts [Electronic resource]. – Cape Town, 2024. – P. 12-13. – URL: http://inis.jinr.ru/sl/NTBLIB/IASEN-2024-P12.pdf. – Bibliogr.:5.

The low-energy multipole spectrum in isotopes 250-260No is investigated in the framework of fully self-consistent Quasiparticle-Random-Phase-Approximation (QRPA) method with Skyrme forces (SLy6, SkM* and SVbas) is applied. The main attention is paid to nuclei 252No and 254No, where we have most of the experimental spectroscopic information [3,4]. In addition to low-energy onephonon collective states (lm=20,22,30,31,32,43) and K-isomers (K = 2-,8-,3+). In general, a goo agreement with the experimental data is obtained. It is shown that, in the chain 250−260No, features of 252No and 254No exhibit essential irregularities caused by a shell gap in the neutron singleparticle spectra and corresponding break of the neutron pairing. The low-energy pairing-vibrational K*p = 0+ state is predicted in 254No.
