A FORMULA TO COMPUTE TOTAL ELASTIC MOTT CROSS-SECTIONS

A formula to compute total elastic Mott cross-sections as well as a tabulation of the constants to compute total Mott cross-sections for 94 elements are presented herein. This formula and the constants have been obtained from the values of total elastic Mott cross-sections computed by Czyzewski et al. (1990) using Thomas-Fermi-Dirac atomic potentials for atomic numbers greater than 54 and Hartree-fock potentials for atomic numbers less than 55. Also, a Monte Carlo program simulating the trajectories of electrons in bulk specimens using our formula of total elastic Mott cross-sections and the single scattering approach is discussed. Values of backscattering coefficients in energy functions for C, Al, Cu, Ag, and Au computed by this program and by other Monte Carlo programs are compared with values measured experimentally by several researchers.
