Elastic scattering of electrons and positrons from H and Ar in the second-order eikonal approximation
Year: 1978
Type: article
Abstract: Wallace's (WSOEA) second-order eikonal approximation is used to calculate elastic differential cross sections for e -or+ -H and e -or+ -Ar scattering at 100 and 500 eV in the angular range 0-20 degrees . The predictions of the WSOEA are compared with those of the partial-wave calculation (PWC), in addition to the results obtained in the first Born approximation (FBA) and Glauber's first-order eikonal approximation (FOEA). The WOSEA shows a definite improvement upon the FBA and the FOEA and yields cross sections in good agreement with the PWC results.
