Radiation tail in ( e , e ′ p ) reactions and corrections to experimental data
1999
We present a direct calculation of the cross section for the reaction ${}^{3}\mathrm{He}{(e,e}^{\ensuremath{'}}p)$ including the radiation tail originating from bremsstrahlung processes. This calculation is compared to measured cross sections. The calculation is carried out from within a Monte Carlo simulation program so that acceptance-averaging effects, along with a subset of possible energy losses, are taken into account. Excellent agreement is obtained between our calculation and measured data, after a correction factor for higher-order bremsstrahlung is devised and applied to the tail. Industry-standard radiative corrections fail for these data, and we use the results of our calculation to dissect the failure. Implications for design and analysis of experiments in the Jefferson-Laboratory energy domain are discussed.
