  Ultra-peripheral heavy ion collisions involve long range electromagnetic
interactions at impact parameters larger than twice the nuclear radius, where
no nucleon-nucleon collisions occur. The first observation of coherent rho^0
production with and without accompanying nuclear breakup, AuAu->Au*Au*rho^0 and
AuAu->Au Au rho^0 respectively, and the observation of e+e- pair production
AuAu->Au*Au*e+e- are presented by the STAR collaboration. The transverse
momentum spectra are peaked at low pT, showing the coherent coupling to the
nuclei. A clear rho^0 signal is observed in the two pion invariant mass
spectrum.
