Bounds are calculated for the oscillation parameters of muon neutrinos, νμ —► vx> from data on quasi-elastic scattering in the neutrino beams of the Institute of High-Energy Physics, Serpukhov. The experiment was carried out jointly by the Institute of High-Energy Physics and the Institute of Theoretical and Experimental Physics. At square-mass differences A m2 ^15 eV2 the mixing ratio is sin2 20 5 9 X 1СГ2 at a 90% confidence level.
