Abstract
Inclusive and exclusive hard-photon (Eγ > 30 MeV) production in five different heavy-ion reactions (36Ar+197Au, 107Ag, 58Ni, 12C at 60A MeV and 129Xe+120Sn at 50A MeV) has been studied coupling the TAPS photon spectrometer with several charged-particle multidetectors covering more than 80% of 4π. The measured spectra, slope parameters and source velocities as well as their target-dependence, confirm the existence of thermal bremsstrahlung emission from secondary nucleon-nucleon collisions that accounts for roughly 20% of the total hard-photon yield. The thermal slopes are a direct measure of the temperature of the excited nuclear systems produced during the reaction.
