The most sensitive experiment to date to search for the muon and electron lepton number violating decay K{sup 0}{sub L}{r_arrow}{mu}{sup {plus_minus}}e{sup {minus_plus}} has detected no events consistent with this process. Based on this result, the 90{percent} confidence level upper limit on the branching fraction is B(K{sup 0}{sub L}{r_arrow}{mu}{sup {plus_minus}} e{sup {minus_plus}}){lt}4.7{times}10{sup {minus}12} . {copyright} {ital 1998} {ital The American Physical Society}
