A binary study of ionization-excitation of H2 for the transitions to the 2sσg and 2pσu excited final ion states was reported. The experimental cross sections exhibit variations with impact energy, confirming a failure of the planar-wave impulse approximation (PWIA) description of the processes. Furthermore, it was discussed and verified that inclusion of the second-order TS mechanisms was crucial for understanding the discrepancies between experiment and PWIA.
