Abstract

Two-particle correlations of direct photons were measured in central 208Pb+208Pb collisions at 158A GeV. The invariant interferometric radii were extracted for 100K(T)300 MeV/c and compared to radii extracted from charged pion correlations. The yield of soft direct photons, K(T)300 MeV/c, was extracted from the correlation strength and compared to theoretical calculations.
