Abstract

The existence of individual low-energy E1 toroidal and compression states (TS and CS) in ²⁴Mg was predicted recently in the framework of quasiparticle random phase approximation (QRPA) model with Skyrme forces. It was shown that the strong axial deformation of ²⁴Mg is crucial to downshift the toroidal strength to the low-energy region and thus make the TS the lowest E1(K=1) dipole state. In this study, we explain this result by simple mean-field arguments. Comparing TS in two strongly axial nuclei, ²⁴Mg and ²⁰Ne, we show that the lowest TS is not a universal phenomenon but rather a peculiarity of ²⁴Mg. The spectroscopy of TS and CS is analyzed and some additional interpretation of these states is suggested.
