ABS>This paper contains the conclusion of the systematic study of K/sup - /p interactions in the Lawrence Radiation Laboratory's 15-in. hydrogen bubble chamber at 1.15 Bev/c. In particular, the elastic and charge-exchange scattering, K*N production, and SIGMA pi reactions are discussed. The procedure used in scanning, measuring, and computer analysis is described in detail. The similarity of total as well as differential cross sections for the three SIGMA pi charge states suggests predominant production from the T = 0 state for this channel. The angular distributions for the SIGMA pi reactions, as well as the elastic and charge-exchange scattering, indicate that partial waves as high as F5/2 must be involved. The analysis of the K/sup -/p pi 0 reactions substantiates the earlier preliminary result of isotopic spin 1/2 for the K* resonance. The angular distributions and correlations in the K/sup -/p pi 0 and K- pi /sup +/n reactions support the conclusion, derived from the previous study of K/sup 0/p pi /sup -/ events, that the K* spin is 0 or 1. A summary of cross sections for all the reactions studied in the experiment is given. (auth)
