Abstract
The nuclear response of a medium-mass nucleus (136Xe) to electromagnetic excitation in a near-relativistic heavy-ion collision was investigated in the reaction136Xe(0.7A GeV)+Pb. From an exclusive measurement of the neutron decay of the excited Xe136 projectiles, strong excitations of giant resonances and, in particular, of the double isovector giant dipole resonance were identified. A resonance energy of 28.3±0.7 MeV, a width of 6.3±1.6 MeV, and a total cross section of 215±50 mb were found for the double giant dipole resonance.
