Positron-hydrogen scattering at intermediate and high energies
J. N. Das,Asoka Biswas +1 more
TL;DR: Positron-hydrogen collision cross sections have been calculated for intermediate and high energies as mentioned in this paper, and an expected broad peak is observed in the results for the total cross section in the intermediate energy range.
Journal ArticleDOI
Hyperspherical partial-wave theory applied to electron–hydrogen-atom ionization calculation for equal-energy-sharing kinematics
TL;DR: In this paper, the authors applied hyperspherical partial wave theory to the calculation of the triple differential cross sections for the ionization of hydrogen atoms by electron impact at low energies for various equal-energy-sharing kinematic conditions.

2S-excitation of atomic hydrogen by electrons at intermediate energies
J. N. Das,N Saha +1 more
TL;DR: The method of Das developed recently to analyse elastic scattering of electrons by atoms has been extended in the present paper to inelastic scatterings as discussed by the authors, which has been applied for the computation of 2S-excitation, cross-sections at two typical intermediate energiesviz. 54.4 eV and 100 eV energies.
Journal ArticleDOI
Elastic scattering of electrons by hydrogen and helium atoms at intermediate and high energies
TL;DR: In this article, an asymptotic analysis of the off-shell amplitudes of electron-hydrogen and electron-helium elastic scattering problems has been performed, and the resulting differential and total cross sections are observed to agree nicely with the experimental results and with the most elaborate theoretical calculations.
Journal ArticleDOI
Positron-helium elastic scattering at intermediate energies
TL;DR: In this paper, the total cross sections for elastic positron-helium collisions have been computed and compared with other theoretical results, and integrated cross sections over small angular regions extending from zero angle are also presented.

Elastic electron-atom scattering at intermediate energies

TL;DR: In this paper, an eikonal-Born-series approach is compared with the usual Glauber approximation, which is shown to be seriously deficient, and applications are made to the elastic scattering of electrons by atomic hydrogen and helium.

Differential Cross Sections for the Elastic Scattering of 1- to 95-eV Electrons from Helium
R. W. LaBahn,Joseph Callaway +1 more
TL;DR: In this article, the authors used the extended polarizationpotential method to calculate the differential cross sections for elastic electron-helium scattering, which was presented in tabular form for collision energies between 1 and 95 eV and a selection of scattering angles from 0 to 180 deg.

Elastic Scattering of Fast Electrons by Helium
FW Byron Jr.,Charles Joachain +1 more
TL;DR: In this article, the analysis of electron-helium eiastic scattering at small and intermediate angles given in a previous paper was extended to include the case of large-angle scattering, and agreement with absolute largeangle measurements is excellent.
