ResumoA search for the decay ${\mathit{K}}_{\mathit{L}}^{0}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\mu}}}^{\ifmmode\pm\else\textpm\fi{}}$${\mathit{e}}^{\ensuremath{\mp}}$ with significantly increased experimental sensitivity has yielded no events. The 90% confidence level limit on the branching ratio is B(${\mathit{K}}_{\mathit{L}}^{0}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\mu}}}^{\ifmmode\pm\else\textpm\fi{}}$${\mathit{e}}^{\ensuremath{\mp}}$)3.9\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}11}$. When this data set is combined with earlier data the upper limit is 3.3\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}11}$.
