摘要：

The parameters obtained from the theoretical analysis of the single-photon spectra observed by the WA98 Collaboration at Super Proton Synchrotron (SPS) energies have been used to evaluate the two-photon correlation functions. The single-photon spectra and the two-photon correlations at relativistic heavy ion collider (RHIC) energies have also been evaluated, taking into account the effects of the possible spectral change of hadrons in a thermal bath. We find that the ratio R-side/R(out)similar to1 for SPS and R-side/R-out<1 for RHIC energy.
