Abstract

High energy γ-rays were measured with a large BaF2 detector in coincidence with fusion residues produced in the 92Mo+40Ar reactions at E A=21 and 26 MeV. The obtained γ-ray spectra were compared with statistical calculations for γ-ray transitions from highly excited nuclei. Contributions of bremsstrahlung in the early stages of the reaction were subtracted. The evolution of the GDR γ-ray yields and the shape of the γ-ray spectra are well reproduced by calculations in which the width of the GDR increases with the excitation energy.
