Comment on analytical evaluation of the Coulomb distortion

The simple treatment of Coulomb distortion in intermediate energy hadron-nucleus scattering developed in the analytic approximation of Amado, Dedonder, and Lenz is implemented. In three examples we compare the impact of the Coulomb distortion calculated with their analytic formula with that calculated by the standard numerical method. These calculations are compared with the data for 800 MeV $p$-${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ and 291 MeV ${\pi }^{\pm }$-${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ elastic scattering. We find that the analytic approximation accurately reproduces the effect of the Coulomb distortion as calculated numerically while illuminating the essentially simple physics involved.
