Quasielastic scattering of neutrinos, ν+n→p⁺+μ^-, was measured in a 30-ton spark-chamber detector. Analysis of the cross section versus momentum transfer yields a value of M_A₁=0.7±0.15 for a single-pole-type axial-vector form factor or M_A₂=1.05±0.2 for a double-pole form factor. No decrease in cross section at low momentum transfer expected due to nuclear effects was observed.
