摘要：

A study of three-body final states produced in 2-prong K-p interactions at 4.57 BeV/c is presented on the basis of 10 500 Guts-fitted events. Abundant production of K*(890) is observed in all three final states (K-π+n, π-pK̄0, and K-pπ0), while K*(1420) is more copiously produced in the final state K-π+n than in the others. The spin density matrix elements for the K*(890) and K*(1420) are given and the production mechanisms are discussed in terms of the one-meson-exchange model. The cross sections for K*(890) and K*(1420) are given. © 1968 The American Physical Society.
