We study the sensitivities of the centroid energy E0 of the isoscalar giant-monopole resonance and the centroid energy E1 of the isoscalar giant-dipole resonance to the effect of relaxation. We find that the energy ratio E1/E0 grows with the relaxation time approaching the experimental value (E1/E0)exp = 1.6 ± 0.1.
