The mass spectrum of muon pairs in the reaction ..pi../sup -/p..--> mu../sup +/..mu../sup -/n has been investigated at momenta 25 and 33 GeV/c. A peak corresponding to the rare decay eta..--> mu../sup +/..mu../sup -/ is distinguished in the mass spectrum. The measured relative probability of this decay (6.5 +- 2.1) x 10/sup -6/ is in good agreement with theoretical estimates.
