摘要：

A calculation of the pion-nuclear T-matrix is performed within the framework of the isobar-hole model. The emphasis here is on a consistent microscopic treatment of Δ-isobar self-energy and particle-hole interactions. This approach allows incorporating medium corrections (Pauli and binding effects together with absorption and reflection contributions) in a non-phenomenological way. The effects of various medium corrections are discussed for the case of π-4He scattering. © 1979.
