Abstract
The strong deformation splitting of the isoscalar giant monopole resonance (ISGMR), recently observed in (alpha, alpha') reaction in prolate Mg-24, is analyzed in the framework of the Skyrme quasiparticle randomphase-approximation (QRPA) approach with the Skyrme forces SkM*, SVbas and SkP(delta). The calculations with these forces give close results and confirm that the low-energy E0-peak is caused by the deformation-induced coupling of ISGMR with the K = 0 branch of the isoscalar giant quadrupole resonance.
