The cross sections for K+p interactions at a center-of-mass energy of 3 GeV (4.3 GeV/c incident momentum) have been determined for the K+pπ+π−, K0pπ+π0, and K0π+π+n final states. The shape of the differential cross section dσdt′ for the quasi-two-body final state K*0(890)+Δ++(1236) is not a single exponential. Characteristics of the low-mass Kππ and pππ enhancements are discussed.

DECAY MOMENTS OF THE K*0 AND DEL++.
We present results on a number of non-diffractive two-body channels contributing to reactions K + p→K 0 π + p and K + p→K + π − π + p. The data come from an exposure of the Mirabelle bubble chamber to an r.f. separated K + beam of 32 GeV/ c at the Serpukhov accelerator. Total cross sections are given for the final states K ∗+ (890) p , K ∗+ (1420) p , K 0 Δ ++ (1232), K ∗+ (890) p , Δ ++ (1232), K ∗0 (1420) Δ ++ (1232), K ∗0 (1780) Δ ++ (1232) and K ∗0 (890) Δ ++ (1950) . The differential cross sections are given for all channels with sufficient statistics. The energy dependence of the total and differential cross sections is studied.
