[en] We have studied the semi-inclusive reactions anti νp → 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 anti νp scattering at a few percent of the inclusive rate. No evidence for D⁰ production was seen in the K_s⁰π⁺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 K_s⁰ are in agreement with results from electroproduction experiments, and we have measured ∫₀₃¹⁰ 1/N_T dn/dz dz_dzsup dN/ dz = 0.029 +- 0.005, which is smaller than the prediction of the Field and Feynman fragmentation model
