Detailed Description

Per-element data used by the Coulomb scattering and Wentzel VI models.

The matrix of coefficients used to approximate the ratio of the Mott to Rutherford cross sections was developed in T. Lijian, H. Quing and L. Zhengming, Radiat. Phys. Chem. 45 (1995), 235-245. Using the same procedure as in Lijian, the coefficients were extended in M.J. Boschini et al, Radiat. Phys. Chem. 90 (2013), 39-66 (doi.org/10.1016/j.radphyschem.2013.04.020) to include positrons and the interaction of electrons and positrons with higher Z nuclei (1 <= Z <= 118).
