Abstract
For a polarized target, pi(3)He interaction is studied in the fixed-center approximation with all rescatterings included. Only the P-33 Wave is taken for the pi N interaction. The nuclear wave function is taken either as a su m of Gaussian functions or as a Faddeev wave function in the s-wave approxi mation. The differential cross sections and asymmetries for elastic pi(+3)H e scattering at the laboratory energies of T-pi = 142, 180, and 256 MeV are calculated. The results are compared with experimental data. (C) 2000 MAIK "Nauka/Interperiodica".
