Pion-hyperon ireractions are considered in the light of a compound model in which a hyperon is taken to be a system of a nucleon plus a meson whose only role is to give the hyperon its observed symmetry properties. It is assumed that pions interact with the nucleon in a hyperon as if the nucleon were free and that pions do not interact appreciably with the new meson. The pion interactions with the LAMBDA and SIGMA which follow from this model are equivalent to the interactions of the elementary particle theorv of Gell-Mann. The pion interactions with the XI are not unique without a further restriction on the model. As an example of this nonone of which is approximately the same as the ordinary nucelon-nucleon potential, while the other is much weaker at large distances. (auth)
