Gluon emission and the transverse momentum (p/sub t/) of partons confined in nucleons were studied using deep-inelastic charged-current neutrino-nucleon interactions. For this analysis we use the flow of hadronic energy in the azimuthal direction around the momentum transfer referenced from the neutrino-muon scattering plane. A five standard deviation asymmetry was found. Analysis of this asymmetry indicates a (p/sub t/) of 0.35 +- 0.12 GeV/c if QCD corrections are included, and 0.56 +- 0.05 GeV/c if they are excluded. Some evidence was also observed for x dependence in p/sub t/. Data were taken at Fermilab in 1982 using a 200 ton (fiducial mass) fine grained calorimeter and a dichromatic neutrino beam.

We report as inelastic neutron scattering study of the uniaxial dilute antiferromagnets Fe/sub 1-x/Mg/sub x/Cl/sub 2/, for x = 0.3, 0.45 and 0.6. The first two samples have long-range AF order. Their spin-wave peaks are broadened by the exchange fluctuations. The x = 0.6 sample oders like an Ising spin-glass with a very short AF correlation length (xi approx. = 10 A). For wavelength lambda less than or equal to xi, the spin-wave peaks are similar to the dilute antiferromagnets, but for lambda less than or equal to 2xi, the peak shapens up and becomes resolution limited at the zone center. We give a simple explanation of this behavior. 13 refs., 1 fig.
