摘要：

To search for spontaneous conversion of muonium to antimuonium with very low background, a new signature was implemented that required the coincident detection of the decay products of the antimuonium atom, the energetic e- and the atomic e+. No conversion events were seen, which sets an improved upper limit of 6.5 x 10(-7) (90% C.L.) on the conversion probability. The corresponding limit on the coupling constant, using a V - A form for the conversion Hamiltonian, is G(MMBAR) < 0.16G(F) (90% C.L.), where G(F) is the Fermi coupling constant.
