Abstract

Differential elastic cross sections for pion-nucleus scattering are calculated by means of a handy and useful local approximation to a Δh model based on a many-body expansion which provides a good description of the different pion-nuclear reaction cross sections. Good agreement with the experimental results is obtained in a wide range of energies around resonance and for different nuclei. The model is particularly useful for the study of heavy nuclei where the original Δh model in its different versions becomes technically prohibitive.
