摘要：

We present tables of the differential, total, and transport cross sections for the elastic scattering of 500-4000 eV positrons by neutral atoms in the atomic number range Z = 1-92. The cross sections were computed by numerically solving the Dirac equation for a central electrostatic field up to a large radius where the atomic potential becomes negligible. The atomic potential used was Hartree-Fock for Z = 1-18 and Dirac-Hartree-Fock-Slater for Z = 19-92. (C) 1998 Academic Press.
