    This paper reports on a search for e from +e+e, allowed by multiplicative but not additive muon conservation, and for e from +e+e, allowed by both. Neutrinos from the Clinton P. Anderson Meson Physics Facility have been used, together with a six-ton Cherenkov counter filled with H2O (D2O) to look for epne+(edppe-). The branching ratio (+e+e)(+ all)=-0.0010.040 is in excellent agreement with the additive law. The cross section (edppe-)=(0.520.18)×10- 40 cm2 agrees with theory.
