Collisional damping of giant resonances in a non-Markovian approach
- INFN, Laboratorio Nazionale del Sud, Viale Andrea Doria (ang. Via S. Sofia), 95123 Catania (Italy)
Employing a non-Markovian collision term, the relaxation rates of giant resonances in nuclei are calculated using a diffuse nuclear surface, and energy and angle dependent cross sections obtained by a parametrization of the nucleon-nucleon scattering data. The calculations show that the collisional damping of giant quadrupole vibrations is sizable and accounts for about 40--60 % of the observed widths, while for giant dipole and giant monopole vibrations it accounts for only 25--30 % of the observed widths.
