Radiation tail in (e,e ' p) reactions and corrections to experimental data- art. no. 014607

We present a direct calculation of the cross section for the reaction He-3( e,e'p) including the radiation tail originating from bremsstrahlung process es. This calculation is compared to measured cross sections. The calculatio n is carried out from within a Monte Carlo simulation program so that accep tance-averaging effects, along with a subset of possible energy losses, are taken into account. Excellent agreement is obtained between our calculatio n and measured data, after a correction factor fur higher-order bremsstrahl ung is devised and applied to the tail. Industry-standard radiative correct ions fail fur these data, and we use the results of our calculation to diss ect the failure. Implications for design and analysis of experiments in the Jefferson-Laboratory energy domain are discussed.
