The cross sections for the elastic scattering of and hyperons on protons have been measured. The hyperons were produced by the interactions of stopping mesons in a hydrogen bubble chamber. The cross section for () elastic scattering is 166±33 mb, at a mean laboratory momentum of 150 . The cross section for () elastic scattering is 84±34 mb at a mean laboratory momentum of 161.5 . These measurements, as well as the results of similar experiments, are compared with several recent theoretical predictions of hyperon-nucleon scattering cross sections.
