Coincidence Measurements of Singleπ+Electroproduction

We have studied the reaction $e^{-}+p\to e^{-}+{\pi }^{+}+n$ by detecting the final electron and pion in coincidence. Data are presented in the region of virtual photon mass squared from -0.18 to -1.2 Ge${\mathrm{V}}^2$, and virtual photoproduction center-of-mass energy and angle from 1.85 to 2.50 GeV and 0 to 20°, respectively.
