The correlation between the couples of high-energy photons (Eγ>30MeV) detected in the reactions induced by a 36Ar beam on 27Al, 112Sn, and 197Au targets at 95 MeV/nucleon has been analyzed with the intensity interferometry technique. Both the size and lifetime of the emitting source have been quantitatively evaluated. Results support the nucleon-nucleon picture as the dominant hard-photon production mechanism.
