AbstractForty-four K− −p low momentum elastic scattering events between 0 and 250 MeV/c have been found by following 265. 12 meters of K− meson tracks, backward from their capture points in nuclear emulsion. The total scattering cross-section is plotted as a function of kaon momentum and this is fitted with the s-wave zro-effective-range theory with the scattering lenghts A0 = −1.1 + 0.55 i, A1 = −0.20 + 0.44 i for the isotopic spin T = 0 and T = 1 channel respectively. Further evidence for s-wave interaction is discussed through the angular distribution in the center-of-mass system for the elastic events.
