Another possible manifestation of the energy-dependent width of the giant dipole resonance.

Abstract

The signals of the energy dependence of the giant dipole resonance width, obtained earlier in neutron radiative capture in the vicinity of the neutron binding energy and in heavy-ion reactions, have been verified against the available experimental data of nucleon radiative capture in the energy range from 5 to 25 MeV and masses Ag100. The study is done within the preequilibrium exciton model. Analyses of low-energy behavior (below 15 MeV) of the radiative capture excitation functions support the use of giant dipole resonance form with the energy-dependent width of the generalized Lorentzian.
