Strong Absorption Model Studies of Pion-Nucleus Scattering Around the Δ Resonance

Abstract

Angular distribution data on the elastic scattering of pions are studied on several nuclei around the Δ resonance in terms of the three-parameter strong absorption model of Frahn and Venter. The parameters thus obtained are used in the analyses of inelastic scattering of pions leading to the lowest as well as higher lying 2+ and 3- states, and the corresponding deformation parameters are extracted.
