INVESTIGATION OF THE INTERACTION BETWEEN 250 TO 270 Mev $pi$$sup +$-MESONS AND CARBON NUCLEI WITH AID OF A PROPANE BUBBLE CHAMBER (in Russian)
Interactions between 250 to 270 Mev pi /sup +/ mesons and carbon nuclei were measured with a propane bubble chamber. The total and differential cross sections for elastic and inelastic scattering of pi /sup +/ mesons as well as the total cross section for absorption and charge exchange of the pi /sup +/ mesons were determined. The prong distributions were obtained for stars containing mesons and for stars not containing mesons. Within the experimental errors, elastic scattering can be described by diffractional scattering for a nucleus with K = 0.54 x 10/sup 13/ cm-/sup -1, V =30 Mev, and R =3.2 x 10/sup -13/ cm. The inelastic scattering data confirm the assumption that mesons interact with separate nucleons in the nucleus and that the number of interactions in the carbon nucleus is not large. Analysis of stars not containing mesons permit one to assert that the absorption of a /sup +/-meson in the carbon nucleus and the subsequent decay of the pi /sup +/-C system cannot be explained on the basis of the evaporation model and so-called cascade process.
