Ad hoc Coulomb corrections to the radiation tail

We give an empirically derived correction factor to an {ital ad} {ital hoc} procedure of including Coulomb corrections in the plane-wave calculation of the radiation tail accompanying elastic electron scattering from the atomic nucleus. Apart from regions of the radiation tail with very large Coulomb distortion effects, our corrected {ital ad} {ital hoc} results agree with a distorted-wave Born approximation calculation of the radiation tail to better than 5%.
