  The damping of the collective vibrations in hot nuclei is studied within the
semiclassical Vlasov-Landau kinetic theory. The extention of the method of
independent sources of dissipation is used to allow for irreversible energy
transfer by chaos weighted wall formula. The expressions for the intrinsic
width of the giant multipole resonances are obtained. The interplay between the
one-body and the two-body channels which contribute to the formation of the
intrinsic width in nuclei is discussed.
