The width of the giant dipole resonance built on excited states of Cu compound nuclei

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

Continuumγ- ray spectra from the decay of59Cu formed at an excitation energy of 100 MeV and angular momenta up to 43ħ by means of the reaction 190 MeV32S +27Al have been measured and analyzed. The parameters of the Giant Dipole Resonance (GDR) have been extracted using the statistical model. The derived GDR width confirms the sizeable broadening of this resonance in59Cu already reported in our earlier investigation at 77 MeV excitation energy (Jcrit=38ħ). Estimates of the GDR width have been performed in the adiabatic approximation. Predicted values account qualitatively for the experimental data of59Cu as well as of the heavier isotope63Cu, in which the broadening was not seen up to 77MeV excitation (Jcrit=35ħ). The present analysis demonstrates the strong sensitivity of the GDR to spin effects in this mass region.
