Abstract：
In the framework of fixed-scatterer field theory,we construct the second order iso-elastic microscopic pion-nucleus optical potential by including two nucleon correlation.The double charge exchange reactions to the double isobaric analog state are calculated by using our theoretical optical potential.For the incident pion energies ranging between 0 and 300MeV,the s and p wave components are included in the πN amplitude.
