Abstract

The toroidal, compression and vortical dipole strength functions in semi-magic ¹²⁴Sn (and partly in doubly magic ^100,132Sn) are analyzed within the random-phase-approximation method with the SkT6, SkI3, SLy6, SV-bas and SkM* Skyrme forces. The isoscalar (T = 0), isovector (T = 1) and electromagnetic ('elm') channels are considered. Both convection j c and magnetization jm nuclear currents are taken into account. The calculations basically confirm the previous results obtained for ²⁰⁸Pb with the force SLy6. In particular, it is shown that the vortical and toroidal strengths are dominated by jc in the T = 0 channel and by jm in the T = 1 and 'elm' channels. The compression strength is always determined by jc. It is also shown that the 'elm' strength (relevant for the (e,e′) reaction) is very similar to the T = 1 one. The toroidal mode resides in the region of the pygmy resonance. So, perhaps, this region embraces both irrotational (pygmy) and vortical (toroidal) flows. © 2013 The Royal Swedish Academy of Sciences.
