Dual Nature of Low-Energy Isoscalar Monopole and Dipole States in Light Nuclei / V.O.Nesterenko // 28th International Nuclear Physics Conference (INPC 2022), Cape Town, South Africa, 11-16 September 2022 [Electronic resource]. – Bristol : IOP Publishing, 2023. – P.012074. – URL: https://doi.org/10.1088/1742-6596/2586/1/012074. – Bibliogr.:35.

Isoscalar monopole (IS0) and dipole (IS1) states located below and around the alpha-particle threshold Sα in prolate 24Mg are investigated within fully self-consistent Skyrme Quasiparticle Random-Phase Approximation (QRPA) approach. It is shown that these states demonstrate strong mean-field (MF) effects: dipole vorticity, deformation-induced monopole-quadrupole (IS0/IS2) and dipole-octupole (IS1/IS3) coupling. At the same time, the density distributions show precursors of a cluster structure. So we get a cluster/MF duality with a strong dominance of MF impact. IS0 QRPA results are compared with iThemba Lab and RCNP (α, α') data. – (Journal of Physics: Conference Series ; Vol.2586) .
