K$sup +$-p INTERACTION FROM 140 TO 642 Mev/c

S>The cross section for the K/sup +/-proton interaction at 140 to 642 Mev/c is found to depend only slightiy on energy. The momentum dependence of the scattering phase shifts below 300 Mev/c is found to be interpretable only in terms of swaves, and to have no p-wave component. The isotropy in the differential cross sections, and the constructive interference with Coulomb scattering, at each of the momenta show that the repulsive s-wave character of the K/sup +/-p T = 1 state persists throughout this region.
