摘要：

A new tabulation of the ratio of the "exact" Mott cross section for unscreened point nuclei to the classical Rutherford cross section for electrons and positrons has been made. Because of the infinite slowly converging series appearing in this ratio we have made two series transformations. With this evaluation the ratio reached convergence within six significant figures after less than a hundred terms and very low computing time. So the ratios evaluated have less relative error than those in the literature and covers a greater range of energy and atomic number.
