This study is intended to identify the decay of a muon into                a positron and a photon (which violates lepton family-number                    conservation) if its branching ratio is greater than 10-13.  The                existing limit of 5x10-11 will be improved by a factor of 500.                  The decay is distinguished from background through the unique                   appearance of the gamma-ray and a positron each with an energy of               52.8 MeV in opposite directions and in time coincidence.  The                   experiment (under the acronym MEGA) will be executed at the Los                 Alamos Meson Physics Facility as a collaborative effort of a                    number of institutions.  In the minimal standard model of the                   weak interaction lepton family-number violation is not required.                However extensions of the standard model permit lepton                          family-number violation to some level.  The MEGA experiment is                  probing the physics beyond the minimal standard model.
