Abstract

Based on a scan for converted

e^{+} e^{-}

pairs in a large neutrino exposure of the Argonne National Laboratory twelve-foot bubble chamber, we report an upper limit of

m_{ν_{μ}} Γ_{ν_{μ}} < 4.6 \times 10^{- 4}

MeV/sec for the process

ν_{μ} \to γ + X

, where

X

satisfies appropriate conservation laws.
