摘要：

The transport mean free path, or transport cross section, is tabulated for the elastic scattering of electrons and positrons in solid matter by means of a correction factor tc applied to the result of a simple screened Rutherford cross section. The correction factor table is based on differential cross-section calculations using a combination of partial-wave analysis (PWA), the Wentzel-Kramers-Brillouin approximation, and the Born approximation, and covers kinetic energies from 100 eV to 20 MeV. Results at low energies are compared with PWA calculations of higher accuracy. Nuclear size effects are discussed but not explicitly included. Applications are discussed.
