Inelastic scattering and absorption of (195 plus or minus 15) Mev pi / sup +/ mesons by carbon and lithium tons were studied with a cloud chamber in a magnetic field. The total and differential inelastic scattering cross sections and also the total cross section for exchange scattering and absorption of pi / sup +/ mesons were determined. The experimental data obtained are compared with the results of calculation of a cascade in the carbon nucleus, and it is shown that inelastic scattering of mesons can be satisfactorily described on the basis of the pair collision hypothesis. It is shown that primarily only two nucleons of the nucleus par ticipate in the act of absorption of a (195 plus or minus 15) Mev pi /sip +/ meson. The probabiiity for meson capture by n,p pairs is 2 to 3 times larger in this case than the probability for capture by pairs of identical nucleons. (auth)
