    "abstract": "Recently a new technique for the production of muon ($\\mu^+$) and muonium\n($\\mu^+e^-$) beams of unprecedented brightness has been proposed. As one\nconsequence and using a highly stable Mach-Zehnder type interferometer, a\nmeasurement of the gravitational acceleration $\\bar{g}$ of muonium atoms at the\nfew percent level of precision appears feasible within 100 days of running\ntime. The inertial mass of muonium is dominated by the mass of the positively\ncharged - antimatter - muon. The measurement of $\\bar{g}$ would be the first\ntest of the gravitational interaction of antimatter, of a purely leptonic\nsystem, and of particles of the second generation.",
