Measurement of Electron Scattering in Carbon to Compare with a Muon Experiment

A measurement of the inelastic scattering of high-energy electrons in carbon has been carried out with the express purpose of obtaining an experimental cross section to compare with a recently-completed measurement of muon scattering. A scaling law which connects the electron result with the (higher-energy) muon result is described. Results for the summed (elastic plus all inelastic) cross section at two values of the muon scattering angle are presented. At the smaller angle (momentum transfer \ensuremath{\sim}200 Mev/c) agreement with the theoretical (Drell-Schwartz) sum rule is good; at the larger one (\ensuremath{\sim}280 Mev/c) it is poorer but within the experimental and theoretical uncertainties. Comparison with the muon results does not alter the previous conclusion: That no muon scattering anomaly is seen.
