Description

Inclusive and exclusive γ-ray spectra have been measured in the reaction /sup 40/Ar+ /sup 158/Gd at 44 MeV/nucleon. Impact-parameter selection has been provided by various coincidence conditions with a forward-angle particle detector. The γ yield for E/sub γ/>25 MeV is consistent with emission from the nucleon-nucleon system and decreases strongly for larger impact parameters. Below 25 MeV, the photons originate from statistical decay of the excited fragments with a strength function dominated by giant resonances. The observed γ yields provide information on the excitation energies of the reaction products
