DOUBLE DIFFERENTIAL CROSS SECTIONS FOR ELECTRON IMPACT IONIZATION OF HELIUM

doi:10.1088/1004-423X/8/3/002

Abstract

Abstract The double differential cross sections for electron impact ionization of helium at incident energies of 200 eV, 100 eV and 64.6 eV have been calculated in the BBK model. The present results are found to be in generally good agreement with the latest measurements of R$\ddot{\rm o}$der et al. and the theoretical results of the convergent close-coupling method although some quantitative discrepancy remains.
