Abstract：
Damping of giant resonance in hot nuclei is investigated using time dependent twobody correlation density matrix theory (TDDM) at several finite thermal excitation energies corresponding to temperatures T =0—6MeV. The results are obtained by solving numerically the set of coupled equations of motion for the one body density matrix ρ (11′;t) and the twobody correlation function C ₂(12,1′2′;t), and compared with the results from different microscopic theoretical approaches. The thermodynamic properties of hot nuclei are also presented. It is shown that the TDDM can describe well the damping of giant resonance and the thermodynamic properties of hot nuclei.
