Coulomb and nuclear excitation of giant dipole resonances in (a,a') inelastic scattering
Cross sections of inelastic a-particle scattering to isovector giant dipole resonances are calculated including both nuclear and Coulomb excitation. It is shown that the calculated cross sections are rather small and can be safely neglected for bombarding energies less than 200 MeV in determining the strength of the giant monopole resonance. This conclusion contradicts that of a recent report m...
متن کاملCoulomb Excitation of Double Giant Dipole Resonances
We implement the Brink–Axel hypothesis for the excitation of the double giant dipole resonance (DGDR): The background states which couple to the one–phonon giant dipole resonance are themselves capable of dipole absorption. These states (and the ones which couple to the two–phonon resonance) are described in terms of the Gaussian Orthogonal Ensemble of random matrices. We use second–order time–...
متن کاملGiant Dipole Resonance Built on Highly Excited States of 120Sn Nuclei Populated by Inelastic a Scattering
High energy g rays from the decay of the giant resonance in hot Sn nuclei were measured in the excitation energy range of 30–130 MeV. The excited nuclei were populated by inelastic scattering of a particles at 40 and 50 MeVynucleon. The resonance width was observed to increase monotonically with increasing excitation energy, from 5 MeV at the ground state to ,12 MeV at the largest excitation en...
متن کاملGiant dipole resonance built on highly excited states of 120Sn nuclei populated by inelastic alpha scattering.
High energy g rays from the decay of the giant resonance in hot Sn nuclei were measured in the excitation energy range of 30–130 MeV. The excited nuclei were populated by inelastic scattering of a particles at 40 and 50 MeVynucleon. The resonance width was observed to increase monotonically with increasing excitation energy, from 5 MeV at the ground state to ,12 MeV at the largest excitation en...
متن کاملExcitation-energy dependence of the giant dipole resonance width.
High-energy y rays have been measured in coincidence with heavy fragments in deeply inelastic reactions of ' 6xe+ Ti at 18.5 MeV/nucleon. The giant dipole resonance (GDR) strength function is deduced from an analysis of the photon spectra within the statistical model. The GDR width I is studied as a function of the fragment excitation energy E*. A saturation at about I =10 MeV is observed for E...
