Abstract
A formula is presented for computing the polar angle of collisions from partial elastic Mott cross‐sections. It will be useful in Monte Carlo simulations of electrons' trajectories in solids and is based on the Newbury and Myklebust (1981) expression. It also is valid for all energy ranging from 0.1 to 30 keV. Also given is the tabulation of the constants of this formula to compute polar angles of collisions for the first 94 elements of the periodic table. The constants of this formula have been obtained by the numerical integration of the values of partial Mott cross‐sections computed by Czyżewski et al. (1990) using Thomas‐Fermi‐Dirac atomic potentials for atomic numbers >54 and Hartree‐fock potential for atomic numbers <55.Keywords
