Moments of Inertia in Light Deformed Nuclei: Pairing and Mean-Field Impacts / V.O.Nesterenko, M.A.Mardyban, [a.o.] // International Journal of Modern Physics E [Electronic resource]. – 2024. – Vol. 33, No. 5. – P. 2450021. – URL: https://doi.org/10.1142/S0218301324500216. – Bibliogr.: 45.
The dependence of the moment of inertia J on the pairing and axial quadrupole deformationin 24Mg and 20Ne was investigated. The study is based on quadrupole-constrained calculationswith three cranking approaches for J (Inglis–Belyaev, Thouless–Valatin, adiabatic time-dependent Hartree–Fock) and a representative set of Skyrme forces (SVbas, SkM*, SLy6).At variance with macroscopic collective models, the calculations predict the specific regime dJ =d < 0 at *b 0:5 (24Mg) and *b*> 0:6 (20Ne), where the pairing breaks down. This regime isexplained by two effects: full break up of the pairing and specific evolution of a single dominantparticle–hole (1ph) con¯guration with . The analysis of experimental data for the ground-staterotational bands in 24Mg and 20Ne shows that such regime is possible at low spins.
