Abstract

The systematics of the isovector Giant Dipole Resonance (GDR) is studied via the microscopic semi-classical Vlasov method. The calculated results of the peak energy and the widths (FWHM) of the GDR strength distribution can reproduce the experimental data and follow the empirical formula. The isospin effects on the peak energy and the widths of the GDR strength distribution are found small and these effects increase slightly with the (N - Z)/A. The characteristics of the GDR have been studied as a function of the temperature in very heavy compound systems (A > 300). The interplay between one-body damping and two-body damping is also discussed.
