Deformation effects in Giant Monopole Resonance
The isoscalar giant monopole resonance (GMR) in Samarium isotopes (from
spherical Sm to deformed 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.Comment: 6 pages, 4 figures, proceedings of 11th Intern. Spring Seminar on
