Phys. Rev. Lett. 85, 1827–1830 (2000)Electromagnetic Cross Sections of Double Giant Dipole Resonances in 136Xe and 208Pb within the Phonon Damping ModelReceived 21 April 2000; published in the issue dated 28 August 2000 The electromagnetic cross sections of the double giant dipole resonances (DGDR) in 136Xe and 208Pb are calculated using the strength functions obtained within the phonon damping model. The parameters of the model have been selected to describe reasonably well the single giant dipole resonance in these nuclei. The results are found in an overall agreement with the recent experimental data for the DGDR cross sections in exclusive measurements at near-relativistic energies. © 2000 The American Physical Society URL:
