✦ Synopsis

High energy photon spectra have been measured in several 5SNi induced reactions at 30A MeV incident energy. A two source analysis of the data has been performed using a two exponential parameterization of the associated gamma spectra. The relative intensity of the two components has been deduced as a function of the total mass of the interacting system and of the impact parameter. To attempt a characterization of the emission sources, correlations between photons and IMF's have been measured for the first time.

The emission of hard photons and pre-equilibrium protons has been investigated in exclusive experiments performed with MEDEA detector. The observation of the 7-proton anticorrelation indicate that the dominant production mechanism is the first chance neutron-proton collisions. Very energetic protons
