Giant dipole resonance in the statistical decay ofCu63,Kr76, andCs127compound nuclei

Abstract
The spectral shapes of high energy gamma rays emitted in the decay of excited Cu63, Kr76, and Cs127 compound nuclei are well reproduced by statistical model calculations which include a giant dipole resonance 1-1.5 MeV lower in energy than the ground-state giant dipole resonance. No evidence is found for a dependence of the giant dipole resonance strength function on spin.
