Abstract

We review earlier cross section data sets for electron-collisions with H₂, O₂, CO, CO₂, H₂O and N₂O, updated here by experimental results for their electronic states. Based on our recent measurements of differential cross sections for the electronic states of those molecules, integral cross sections (ICSs) are derived by applying a generalized oscillator strength analysis and then assessed against theory (BEf-scaling [Y.-K. Kim, J. Chem. Phys. 126, 064305 (2007)]). As they now represent benchmark electronic state cross sections, those ICSs for the above molecules are added into the original cross section sets taken from the data reviews for H₂, O₂, CO₂ and H₂O (the Itikawa group), and for CO and N₂O (the Zecca group).
