A new measurement is described which sets an upper limit on the coupling constant for conversion of muonium (..mu../sup +/e/sup -/) to antimuonium (..mu../sup -/e/sup +/) of 42G/sub F/, where G/sub F/ is the Fermi coupling constant. Muonium atoms were formed in layers of fine silica powder separated by vacuum drift regions. The presence of ..mu../sup -/ was searched for using the signature of a Ca 2P-1S muonic x ray from calcium oxide layers adjacent to the drift regions. Results were also obtained with an Ar target.
