Abstract

The dynamic collective model has been extended to quadrupole giant resonances in spherical nuclei. The splitting of giant dipole and giant quadrupole resonances due to their coupling to surface vibrations has been calculated for Sn isotopes. Agreement with recent $\ensuremath{\gamma}$-absorption measurements of the Livermore group has been found.
