Spin Effects in Pion Nuclear Scattering

The first measurements of pion scattering and pion single charge exchange on polarized complex nuclei, obtained at PSI, LAMPF and TRIUMF, are reported. Large spin effects were obtained in pion elastic and inelastic scattering (3+, 2.19 MeV state) in \({}^{6}\overrightarrow{\text{Li}}\). Contrary to these results only small analyzing powers were obtained for pion elastic scattering from \({}^{13}\overrightarrow{\text{C}}\) and \({}^{15}\overrightarrow{\text{N}}\). However, in pion single charge exchange on \({}^{13}\overrightarrow{\text{C}}\) large spin effects were seen. The data are compared with theoretical predictions applying the momentum space optical model and the ∆-hole model, as well as DWIA. In general, the agreement is quite poor, and there are indications that the scattering models as well as the nuclear structure input must be refined.
