We have studied the semi-inclusive reactions ν̅ p→μ+V0X and νp→μ-V0X, and measured the fractional rate for producing one or more neutral strange particles in these reactions to be 0.16±0.03 and 0.15±0.04, respectively. We have observed K-(892) and Σ-(1385) production in ν̅ p scattering at a few percent of the inclusive rate. No evidence for D0 production was seen in the KS0π+π- final state. The distributions in the standard deep-inelastic kinematic variables are presented for events with strange particles and compared to those for the other charged-current data. The fragmentation properties of events containing a KS0 are in agreement with results from electroproduction experiments, and we have measured ∫0.31.0(1/NT)(dN/dz)dz=0.029±0.005, which is smaller than the prediction of the Field and Feynman fragmentation model.
