Abstract: For the process e$\\sp+$e$\\sp-\\rightarrow \\mu\\sp+\\mu\\sp-$(n$\\gamma$), the cross section and forward-backward charge asymmetry are measured at the highest ever center of mass energies which ranged from 130 to 183GeV. The data originates from 85pb$\\sp{-1}$ of integrated luminosity collected with the L3 detector at LEP. The measured muon pair cross section and forward-backward asymmetry agree with the Standard Model prediction with a $\\chi\\sbsp{\\rm SM}{2}/N$ =.61 with 10 degrees of freedom. A mass limit on an additional heavy, neutral gauge boson of M$\\sb{\\rm Z'} >$ 315GeV is set using muon pair production alone, rising to M$\\sb{\\rm Z'} >$ 805GeV when all final states are considered. A search for an excited lepton decaying via $\\mu *\\rightarrow\\mu\\gamma$ excludes such objects with electromagnetic coupling up to 183GeV.
