Summary:
We have examined (1) the elastic scattering of pions from the isodoublet /sup 3/He and /sup 3/H and (2) the single charge-exchange reaction /sup 3/H(..pi../sup +/,..pi../sup 0/)/sup 3/He using a formalism which incorporates the ..pi..-N multiple scattering to all orders. Emphasis is placed on numerical results which illustrate those features of the differential cross sections that are expected to be of interest to the experimentalist. Realistic nuclear densities corresponding to the form factors of elastic electron scattering were used. Charge-exchange cross sections are presented in terms of angular distributions for both the ..pi../sup 0/ and the recoil nucleus. In elastic scattering, Coulomb-nuclear interference effects are significant at incident pion kinetic energies of less than 100 MeV; form factor effects are apparent at large momentum transfer. Comparison of data and theory for ..pi../sup +/ - /sup 3/He with that for ..pi../sup -/ - /sup 3/He (or the conjugate ..pi../sup +/ - /sup 3/H) will provide a test of the convergence of the fixed scatterer, multiple-scattering formalism utilized in this report. 21 figures.
