An investigation has been made into the elastic scattering of hyperons on hydrogen. The experiment was based on a sample of 12 000 particles formed in a propane bubble chamber by the interactions of 1.15-Bev/c mesons. A total track length of 210 meters in the energy range 100 to 700 Mev has been examined.
Ten examples were found of the reaction , and six of the reaction . The estimates of the cross sections for the two processes are, respectively, mb and mb. The scattering angle distributions in the c.m. system appear isotropic for the particles, and peaked forward for the particles. The results are discussed in relation to various theoretical predictions, and, in particular, some evidence is found favoring the Gammel-Thaler method of treating the triplet odd-parity nucleon-nucleon potential.
