The energy and system size dependence of pseudorapidity ($\eta$) and multiplicity distributions of photons are measured in the region -2.3 $\leq$ $\eta$ $\leq$ -3.7 for Cu + Cu collisions at $\sqrt{s_{NN}}$ = 200 and 62.4 GeV. Photon…

The fact that nuclei have diffuse surfaces (rather than being simple spheres) has dramatic consequences on the interpretation of RHIC heavy-ion data. The effect is quite small (but not negligible) for central collisions, but gets…
