N2 - Direct electron impact ionization cross sections for all ionization stages of Kr were calculated with the modified relativistic binary encounter Bethe model (MRBEB), and excitation-autoionization cross sections were evaluated using the first order many body theory (FOMBT) for Kr+, Kr5+, Kr6+, Kr10+, Kr15+ and Kr17+. Our results were compared to configuration-averaged distorted-wave (CADW) calculations, the widely used Lotz formula, and available experimental results. Comparison between direct ionization cross sections for the Ar and Fe isonuclear series was also done with the goal of assessing the versatility of the MRBEB model.
