Deformation effects in Giant Monopole Resonance

Nuclear Theory 2016-02-10 v2

Abstract

The isoscalar giant monopole resonance (GMR) in Samarium isotopes (from spherical 144^{144}Sm to deformed 148154^{148-154}Sm) is investigated within the Skyrme random-phase-approximation (RPA) for a variety of Skyrme forces. The exact RPA and its separable version (SRPA) are used for spherical and deformed nuclei, respectively. The quadrupole deformation is shown to yield two effects: the GMR broadens and attains a two-peak structure due to the coupling with the quadrupole giant resonance.
