The Radiation Tail in (e,e'p) Reactions and Corrections to Experimental Data

Abstract

We present a direct calculation of the cross section for the reaction 3He(e,e'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 miserably 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-Lab energy domain are discussed.
