Abstract
A FNAL E799 Collaboration has carried out a search for the lepton-family number violating decay π0 → μ±e∓ using π0's produced from KL → π0π0π0 decays in flight. No events were observed. Assuming that lepton-family number violation is charge independent, the 90% confidence level upper limit on 1 2[BR(π0 → μ+e-) + BR(π0 → μ-e+)] was determined to be 8.6 × 10-9. © 1994.
