A survey of the elastic charge-exchange reactions is presented. The charge-exchange cross sections are evaluated in a coupled-channel framework with optical potentials obtained from the Kisslinger and Laplacian models for the pi-nucleon off-shell scattering amplitude. Considerable differences between these two models are obtained for pion kinetic below the pi-nucleon (3, 3) resonance. The effect of two-nucleon correlations is included by calculating the second-order pi-nucleus optical potential. It is found that this effect dominates the charge-exchange reactions at energies of about 100 MeV. (AIP)
