The interaction of positive and negative pi -mesons with helium nuclei at energies of 273 and 330 Mev was studied using a diffusion cloud chamber. Quasifree scattering on neutrons and protons, multiple scattering, and absorption of the mesons were discriminated. The total inelastic interaction cross sections were (145 plus or minus 15) x 10/sup -27/ cm/sup 2/ for E/sub pi / = 273 Mev and (103 plus or minus 10) x 10/sup -27/ cm/sup 2/ for E/sub pi / = 3 30 Mev. The relative probabilities for quasifree scattering on neutrons and protons through angles>45 deg in the laboratory coordinate system were found to agree with the corresponding probabilities for scattering on free nucleons. The probabilities for multiple scattering processes were found to be 0.24 plus or minus 0.06 for E/sub pi / =273 Mev and 0.29 plus or minus 0.05 for E/sub pi / =330 Mev. The angular distribution of inelastically scattered pi mesons was compared with the Watson-- Zemach calculations. (auth)
