Upper limit for muon-electron conversion in sulfur

Journal Article · · Phys. Rev. Lett.; (United States)
The anomalous neutrinoless conversion of stopped negative muons into electrons has been searched for in sulfur. No electron with an energy above 93 MeV was found. The upper limit for the branching ratio relative to ordinary muon capture is 4 x 10/sup -10/ at the 90% confidence level.
