It has been suggested recently that the extrapolation procedure used to determine the The effects of -N coupling constant from pion photoproduction angular distributions could be applied to K-meson photoproduction data to obtain the parity of the K/sup +/ meson. This suggestion is discussed, and the available data are analyzed. (W.D.M.) l4736 It was recently observed that emulsion data for the total elastic scattering of K- on protons may indicate a broad peaking in the cross section at , hardness, 25 Mev, and that this peak could be interpreted in terms of a J = i/2 resonance of the K-p system. An explanation of the broad peaking at low energiess within the framework of the s- wave zero-range analysis, is pointed out. lf the K--p interaction is assumed "repulsive," the destructive interference with the attractive Coulomb interaction will cause the integrated cross section to fall below the value in the absence of the Coulomb field. At low energies this effect is sufficient to cause the integral of the elastic differential cross section to behave as implied by experiment. (W.D.M.)
