Title: Ultra-peripheral collisions of relativistic heavy ions

Abstract

We report the first observation of exclusive {rho} production in ultra-peripheral collisions at RHIC. The {rho} are produced electromagnetically at large impact parameters where no hadronic interactions occur. The produced {rho} have a small perpendicular momentum, consistent with production that is coherent on both the photon emitting and scattering nuclei. We observe both exclusive {rho} production, and {rho} production accompanied by electromagnetic dissociation of both nuclei. We discuss models of vector meson production and the correlation with nuclear breakup. We also observe e{sup +}e{sup -} pair production in these ultra-peripheral collisions.
