Coincidence Measurement of Backwardπ0Electroproduction

Abstract

We have studied the reaction $e^{-}+p\to e^{-}+p+{\pi }^0$ by detecting the final electron and proton in coincidence. The data cover the region of virtual photon mass squared from -0.19 to -1.4 Ge${\mathrm{V}}^2$, and virtual photoproduction center-of-mass energy and angle from 1.84 to 2.50 GeV and 0° to 35°, respectively.
