Abstract
Ultra-peripheral heavy ion collisions involve long range electromagnetic interactions at impact parameters larger than twice the nuclear radius, where no hadronic nucleon-nucleon collisions occur. The first observation of coherent rho production with and without nuclear breakup, along with the observation of ee pair production, are reported by the STAR collaboration.
