Triple differential cross section for single ionization of H₂ by electron impact

The triple differential cross section (TDCS) for the (e, 2e) ionization of hydrogen molecule is calculated using the molecule distorted-wave Born approximation (MDWBA). Distorted waves are obtained by solving momentum-space coupled-channel Lippmann-Schwinger equations, including the ground state and the lowest-lying electronic state of b³Σ_u. TDCS at the incident energy 100 eV in coplanar asymmetric geometry are reported. The present calculations are compared with the available experimental measurements and the theoretical results.
