Abstract：
The isoscalar giant surface resonance and giant dipole resonance of highly excited nuclei are discussed. Excitation energies of the giant modes in ²⁰⁸Pb are calculated in a simplified model, using the concept of energy weighted sum rule (EWSR), and the extended Thomas-Fermi approximation at finite temperature is employed to describe the finite temperature equilibrium state. It shows that EWSR and the energy of the resonance depend weakly on the temperature of the system. The weak dependence is analyzed.
