We have studied the semi-inclusive reactions anti ..nu..p ..-->.. ..mu../sup +/V/sup 0/X and ..nu..p ..-->.. ..mu../sup -/V/sup 0/X, 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/sup -/(892) and ..sigma../sup -/(1385) production in anti ..nu..p scattering at a few percent of the inclusive rate. No evidence for D/sup 0/ production was seen in the K/sub s//sup 0/..pi../sup +/..pi../sup -/ 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/sub s//sup 0/ are in agreement with results from electroproduction experiments, and we have measured ..integral../sub 0/ /sub 3//sup 1/ /sup 0/ 1/N/sub T/ dn/dz dz/sub dz//sup dN/ dz = 0.029 +- 0.005, which is smaller than the prediction of the Field and Feynman fragmentation model.
