Abstract：
The μ pair decayed from Z⁰ is a good means to check the quality of reconstruction program in L3 Cosmic experiment. This paper describes the method of selecting Z⁰→μ⁺μ^－events from data sample recorded during April,May,August and September,2000 when the LEP was running at Z⁰ energy.The momentum resolution of (5.47±0.25)% for 45 GeV muon is obtained.
