Pion production by 2.65 BeV/c K ' mesons interacting in the BNL 20" hydrogen bubble chamber has been investigated. It is found that these inelastic events are dominated by K*(891) and ~~(1236) production. Based on 537 three- and four-body events, the cross sections for production of K"p $ and K+p$n- are 2.7 4 0.3 mb and 2.5 + 0.2 mb respectively. The three body final states contain 56 % K*p and 32 % N*K " while the four body states contain 9 % K*p$, 1 % N*K7? and 53 % K*N*. Resonance production is compared with predictions of several versions of the one meson exchange model. Although agreement with the data is not exact, the models tend to reproduce a number of qualitative features of the experimental results.
