We report calculations for exclusive ionization-excitation Compton cross sections, both total and differential in energy transfer, for n = 3-5 of the negative hydrogen ion and the helium atom. We find that, unlike the cross section for n = 1 and 2, the exclusive cross sections for n 3 are not very sensitive to atomic parameters such as geometric size and electron correlation. We discuss differences and similarities of the cross sections when different initial-state wavefunctions are used, and compare with the Compton cross section for collision of a photon with a free electron. Our calculations have been carried out for photon energies from 6 to 60 keV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
