Abstract
Neutral strange particle production in\(\bar v\) Ne charged current interactions is studied using the bubble chamber BEBC, exposed to the CERN SPS antineutrino wide band beam. From a sample of 1191 neutral strange particles, the inclusive production rates are determined to be (15.7±0.8)% forK 0 mesons, (8.2±0.5)% for Λ, (0.4±0.2)% for\(\bar \Lambda \) and (0.6±0.3)% for Σ0 hyperons. The inclusive production properties ofK 0 mesons and Λ hyperons are investigated. The Λ hyperons are found to be polarized in the production plane.

The rates reported in a previous publication [11] were similar for ν interactions but slightly different for 216-2 interactions: theK 0 production rate in 216-3 and 216-4 interactions was (21.9±2.5)% and (22.2±1.8)% respectively, whereas the Λ production rate was (8.2±1.2)% and (7.0±0.8)% respectively
