A search for the lepton flavor violating {mu}{sup +}{r_arrow}{ital e}{sup +}{gamma} decay using polarized muons is proposed. By measuring the angular distribution of {ital e}{sup +}s with respect to the muon spin direction, in particular antiparallel {ital e}{sup +}s, the serious physics background from {mu}{sup +}{r_arrow}{ital e}{sup +}{nu}{nu}{gamma} as well as accidental background from normal muon decay accompanied by a high-energy photon can be suppressed for {mu}{sup +}{r_arrow}{ital e}{sup +}{gamma} with right-handed {ital e}{sup +}. In addition to the enhancement of the sensitivity, the angular distribution would discriminate among different extensions to the standard model, once the signal is observed. {copyright} {ital 1996 The American Physical Society.}
