摘要：

Differential elastic cross sections for pion-nucleus scattering are calculated by means of a handy and useful local approximation to a DELTA-h model based on a many-body expansions 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 DELTA-h model in its different versions becomes technically prohibitive.
