Abstract: (Elsevier)

Bubble chamber pictures have been scanned for the interactions of stopping K − mesons in hydrogen. New determinations of the ratios γ= K − p →Σ − π + K − p →Σ + π − , R c = K − → charged particles K − p → all final states for K − meson interactions at rest, are presented, as well as the branching ratio B= Σ + → n π + Σ + → n + +, p π 0 . The values found for R c , 0.664±0.011, and for B , 0.488±0.008, are in agreement with previous results. On the other hand, two values, resulting from different methods of analysis, have been found for γ, namely 2.38±0.04 and 2.35±0.07. They agree with one of the two previous precise measurements but are inconsistent with the other.
