Abstract

Analog (π⁺, π⁰) charge exchange on ¹³C in the (3, 3) resonance region is considered within a modified eikonal formalism, which makes use of traditional eikonalization only for pion-nuclear processes, but not for pion-nucleon processes. Corrections to DWIA, based on two-step processes as suggested by Eisenberg and Gal are evaluated. The calculated charge exchange total cross section is found to increase due to these corrections by 15 %, and is still well below the measured one for T_π > 150 MeV.
