摘要：
Within the diffraction theory of multiple scattering, the differential cross sections for elastic and inelastic pion scattering on a 7Li nucleus are calculated for the case where the final nucleus is either in the ground or in the first excited state. The nuclear wave function is set to that in the αt cluster model. The sensitivity of the calculated observables to variations in the type of the wave functions for the alpha-particle and the triton cluster and for their relative motion is investigated. Various multiplicities of scattering and rescattering on the clusters constituting the 7Li nucleus are taken into account, and their contributions to the cross section are revealed. The results of the calculations are compared with experimental data at Eπ=143, 164, and 194 MeV.
