The Giant Dipole Resonance Built on Highly Excited States

  • Chapter
Book cover Advances in Nuclear Dynamics

Abstract

Gamma-rays emitted from hot nuclei of mass around 115 and excitation energies above 300 MeV, formed in the 36Ar + 90Zr at 27 MeV/u, 36Ar + 94Zr at 32 MeV/u and 36Ar + 98Mo at 37 MeV/u, have been measured with the MEDEA multidetector in coincidence with light charged particles and evaporation residues. The γ-ray yield from the decay of the Giant Dipole Resonance is independent of excitation energy and of bombarding energy.The best agreement with the data is obtained by assuming a cut-off the resonace γ-emission above an excitation energy of 250 MeV.
