The MEGA experiment is designed to search for the rare decay μ→eγ with a branching ratio sensitivity of ∼5×10−13. Production data have been taken during 1992 and 1993, and the detector is working as expected. Following a complete analysis, t

We report the results of a measurement of the Lamb shift in the n=2 state of muonium. Muonium atoms in the metastable 2S state were produced by the beam-foil method and the formation rate was determined by observation of the Ly-\ensuremath{\alpha} ph
