Abstract:
From an exposure of the Fermilab 15 ft Neon(64 atomic %)H2 filled bubble chamber to a single-horn-focussed beam, we have found 60 e?X and 35 e+X events, which we compare with 227 μ?X and 202 μ+X events. No statistically significant departures from μ-e universality are seen in the shapes of various differential cross sections.
