Abstract
Damping width of the double giant dipole resonance of Xe-136 excited i n relativistic heavy ion collisions is calculated by diagonalizing a m icroscopic Hamiltonian in a basis containing one-, two- and three-phon on states. The coupling between these states is determined making use of the fermion structure of the phonons. The resulting width of the do uble giant dipole resonance is close to root 2 times the width of the single giant dipole resonance.
