Bryman, D

An upper limit for the branching ratio of the decay ..pi../sup 0/..--> mu..e is determined from existing experimental data to be GAMMA(..pi../sup 0/..--> mu..e)/GAMMA(..pi../sup 0/..-->..all) < 7 x 10/sup -8/(90% C.L.). Phenomenological implications are discussed. The sensitivity of ..pi../sup 0/..--> mu..e decay to the presence of Higgs particles responsible for muon-number violation is found to be considerably lower than for muon-electron conversion in the field of a nucleus.
