Abstract
The STAR Collaboration reports the first observation of exclusive [Formula presented] photoproduction, [Formula presented], and [Formula presented] production accompanied by mutual nuclear Coulomb excitation, [Formula presented], in ultraperipheral heavy-ion collisions. The [Formula presented] have low transverse momenta, consistent with coherent coupling to both nuclei. The cross sections at [Formula presented] agree with theoretical predictions treating [Formula presented] production and Coulomb excitation as independent processes. © 2002 The American Physical Society.
