摘要：

We examine the properties of an atomic system consisting of a muon and antimuon. Expressions are derived for the probability of decay and the hyperfine splitting of the lower levels with allowance for the leading radiative corrections, which are of relative order cy. The results for the lifetimes and the ground-state energy are tau(1(3)S(1))=1.7907(8) x 10(-12) s, tau(1(1)S(0))=0.59547(33) x 10(-12) s, and E(hfs)(1s)=4.23284(35) x 10(7) MHz. The relative probabilities for the various decay channels are calculated; in particular, for the 1(3)S(1) level it is found that Gamma(mu mu->ee gamma)/Gamma(mu mu-->ee) approximate to 15%. Finally, possible applications are discussed. (C) 1998 American Institute of Physics.
