Özet

Collisional damping widths of giant dipole excitations are calculated in Thomas-Fermi approximation by employing the microscopic in-medium cross-sections of Li and Machleidt and the phenomenological Gogny force. The results obtained in both calculations compare well, but account for about 25-35% of the observed widths in Sn-120 and (208)pb at finite temperatures. (C) 2000 Published by Elsevier Science B.V.
