An exclusive study of the hard photon production in the reaction 40Ar+51V at 44 MeV/nucleon has been carried on with the 4π multidetector MEDEA. An anticorrelation effect in the emission of very energetic photons and protons has been observed for the first time. This is a strong indication for the first-chance n-p bremsstrahlung production mechanism.
