Distorted-wave calculation of He(e,2 e) including core-exchange amplitudes

Technical Report:

Abstract

Distorted-wave Born approximation (DWBA) calculations are reported for coplanar symmetric ionization of helium at energies of 100 and 200 eV. The best possible one-configuration incident distorted wave functions together with the capture scattering have been used to produce a better agreement with absolute measurements at 100 eV compared with the previous DWBA calculations. However the discrepancy between experiment and theory at 200 eV for large angles has not been resolved by these modifications. Moreover capture scattering has been found negligible at 28.6 to 200 eV. Similar DWBA calculations for hydrogen close to the threshold are also reported. Very good agreement with experiment has been found at 17.6 eV. 20 refs., 4 figs.
