Abstract
We report on the results of the first measurement of exclusive meson photoproduction on protons for and . Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. The resonance was detected via its decay in the channel by performing a partial wave analysis of the reaction . Clear evidence of the meson was found in the interference between and waves at . The -wave differential cross section integrated in the mass range of the was found to be a factor of about 50 smaller than the cross section for the meson. This is the first time the meson has been measured in a photoproduction experiment.
