TY - THES TI - Interferometry of hard photons in heavy-ion collisions; Interferometrie de photons durs dans les collisions entre ions lourds AB - Heavy ion collisions offer the unique opportunity to study interference effects between independent hard photons (energies above 25 MeV). The theoretical basis of interference is presented in the framework of classical as well as quantum theory. Experiments use the photon spectrometer TAPS, a modular array of BaF{sub 2} crystals covering 30% of the solid angle. The properties of the spectrometer and the data analysis techniques are described for the experiment {sup 129}Xe + {sup 197}Au at 44 MeV/u, the very first dedicated to the study of photon correlation function. Data are interpreted using GEANT3 simulations to analyse the effect of the method as well as the response function of the photon spectrometer. A second experiment, {sup 86}Kr + {sup 58}Ni at 60 MeV/u is described briefly, where for the first time the existence of an interference effect between hard photons is observed. 52 figs., 76 refs.
