TOTAL AND TRANSPORT CROSS SECTIONS FOR ELASTIC SCATTERING OF ELECTRONS BY ATOMS

Abstract Tables are given of total cross sections as well as first and second transport cross sections for elastic scattering of electrons with kinetic energies from 100 eV to 1 GeV by neutral atoms with atomic numberZ= 1 to 92. With the information given in the present tables, accurate Monte Carlo simulations of electron multiple elastic scattering can be easily performed. The tabulated cross sections have been calculated by using the Dirac partial wave method with screened potentials obtained from Dirac–Hartree–Fock atomic electron densities. Exchange effects are introduced by means of the local approximation of Furness and McCarthy. Nuclear size effects are accounted for in the Born approximation by using Helm's nuclear form factor.
