Abstract:
Under the quasi-Δ33 doorway state model, The Tmatrix for π-12C elastic scattering at the (3.3) resonance region is calculated. The emphasis is put on that how the variety of the parameters in the model, which reflect many body correction in π-nucleus interaction and the properties of Δ(1232)-hole interaction, influences the angular distribution and total cross section. Acomparison between between theory and experiment is performed, and the agreement is satisfactory. It is interesting that in order to fit existed data, especially the angular distribution, the spin-orbit coupling interaction strength has to be positive which differs from the case for nucleon where it is negative.
