Abstract
We report here small-angle absolute elastic-scattering cross sections for 25-keV electrons scattering from helium in a crossed-beam apparatus. Our results disagree with those reported by Geiger and Morón-León, but agree with relativistic first Born cross sections obtained with an explicitly correlated wave function. Our results are in agreement with those of Coffman, Fink, and Wellenstein, who used a different approach to measure the elastic differential cross sections. Our experimentally measured x-ray incoherent-scattering factors also agree with the results obtained with the explicitly correlated wave function.Keywords
