Abstract
The high energy gamma-rays from the fusion-evaporation reaction 101 MeV F-19 + Ta-181 have been measured in coincidence with different gamma-ray fold windows or discrete gamma-rays in final residual nuclei. The line-shape Analysis of the high energy gamma-ray spectra confirms the large deformation of the Pb-200 nuclei at high angular momenta. Coincidences with discrete gamma-transitions evidence a strong correlation between gamma-rays in the Giant Dipole Resonance region (E-gamma greater than or equal to 8 MeV) and final evaporation residues.
