Abstract：
In the framework of the fixed-scattering field theory, we construct microscopically a second-order pion-nucleus Iso-elastic optical potential by including two-nucleon correlations. The double charge exchange reactions to the double isobaric analog states are calculated by using our theoretical optical potential. For the incident pion energies ranging from 0 to 300 MeV, the Sand Ppartial waves are included in the πN amplitude.
