We present the multiplicity and pseudorapidity distributions of photons produced in Au + Au and Cu + Cu collisions at √s[subscript NN] = 62.4 and 200 GeV. The photons are measured in the region - 3.7 < η < - 2.3 using the photon multiplicity detector in the STAR experiment at RHIC. The number of photons produced per average number of participating nucleon pairs increases with the beam energy and is independent of the collision centrality. For collisions with similar average numbers of participating nucleons the photon multiplicities are observed to be similar for Au + Au and Cu + Cu collisions at a given beam energy. The ratios of the number of charged particles to photons in the measured pseudorapidity range are found to be 1.4 ± 0.1 and 1...
