Quasielastic. nu. /sub. mu. / n scattering at energies 3--30 GeV

Preliminary results are presented on the determination of the energy dependence of the cross section for quasielastic scattering of muon neutrinos by neutrons, ..nu../sub ..mu../+n..--> mu../sup -/+p, in the region 3< or =E< or =30 GeV. From a combined analysis of the total and differential cross sections we have determined the parameter M/sub A/ = 1.00 +- 0.07 GeV/c/sup 2/. In the overlapping energy region the data are in good agreement with the results of other experiments.
