Model Dependence of Pion-Nucleus Total Cross Sections

Richard R. Silbar and Morton M. Sternheim

Phys. Rev. C 6, 764 – Published 1 September 1972

Abstract

We show that pion-nucleus total cross sections are sensitive to the assumed off-shell behavior of the pion-nucleon amplitude. Dependence on energy and nucleon number is discussed, as in an energy-dependent effective nuclear radius arising from the $p$ -wave pion-nucleon interaction.
