The ratio R-italic/sub ..nu../ of the neutral- to charged-current cross sections of neutrinos in iron has been measured in an exposure of the CERN-Dortmund-Heidelberg-Saclay neutrino detector to a 160-GeV/c-italic neutrino narrow-band beam at the CERN Super Proton Synchrotron. The result is R-italic/sub ..nu../ = 0.3072 +- 0.0025(stat) +- 0.0020(syst), for hadronic energy greater than 10 GeV. The electroweak mixing parameter is sin/sup 2/theta/sub W/ = 0.225 +- 0.005(expt ) +- 0.003(theor)+0.013(m-italic/sub c-italic/-1. 5 GeV/c-italic/sup 2/), where m-italic/sub c-italic/ is the charm-quark mass.
