Abstract：
In the frame of DWBA and by including multinucleon effects in the optical potential and transition matrix elements,we calculate ¹³C(π⁺,π⁰)¹⁹N(IAS) reactions.Angular distribution at 165MeV,forward angle excitation function and integrated cross sections for this reactions are studied.A formula for mass dependence of forward differential cross sections is derived.
