Abstract
Based on the Lagrangian of Olsson and Turner, contributions of the second kind of meson exchange current to pion-nucleus double-charge-exchange reactions (, and (, have been evaluated. The calculated results show that the second kind of meson exchange current makes the forward theoretical cross section closer to the experimental data but the long-standing puzzling problem of the location of the minimum of the angular distribution at the energy of 164 MeV has not been solved.
