Abstract Two FORTRAN 77 codes are described which provide a complete description of elastic scattering of electrons and positrons by atoms using the static field approximation with non-relativistic (Schrödinger) and relativistic (Dirac) partial wave analysis. The delivered information includes phase shifts, differential cross-sections, scattering amplitudes and percentage points of the single scattering angular distribution. The scattering field may be internally generated by the codes (which incorpor... Title of program: PWASCH AND PWADIR Catalogue Id: ACJX_v1_0 Nature of problem These codes provide a complete description of elastic scattering of electrons and positrons by neutral atoms. They use the static field approximation with non-relativistic (Schrodinger) and relativistic (Dirac) partial wave analysis. ...
