Elastic scattering of electrons from He, Ne and Ar atoms at 35 keV

The eikonal Born series (EBS) method is applied to the elastic scattering o f electrons by He, Ne and Ar atoms at 35 keV. The differential cross-sectio ns are compared with the numerical results obtained by the partial-wave ana lysis. A simple analytical Dirac-Hartree-Fock-Slater (DHFS) field is used f or these atoms. The results are also obtained by Wallace, Das and modified Das method. An oscillatory nature and a strong forward peak in the cross-se ction are not found at 35 keV. The results are nearer to the experimental d ata of Coffmann and M. Fink as well as numerical results based on relativis tic partial-wave treatment.
