Abstract:We have used a coincidence technique to measure the inelastic x ray scattering spectrum from copper K-shell electrons at an incident energy of 70 keV. We cover a range of momentum transfers tLq over which 0.5 5 qa 5 1.1, where a is the Bohr radius of the copper K-shell. This is a momentum transfer regime in which the impulse approximation is no longer valid. The data presented are compared to the results of a one-electron calculation and agree well in both spectral shape and absolute cross section. In contrast… Show more
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.
