Low-energy pion-nucleus optical potentials

Discusses the local and non-local pion-nucleus optical potentials. It is found that the local potential becomes non-local when two-nucleon correlations are included. The two potentials (including correlations) can be made local through a transformation on the wave function. The new local potentials...

description Discusses the local and non-local pion-nucleus optical potentials. It is found that the local potential becomes non-local when two-nucleon correlations are included. The two potentials (including correlations) can be made local through a transformation on the wave function. The new local potentials agree up to quadratic terms when expanded in powers of the density. The influence of finite-range correlations and off-shell pion-nucleon form factors is also investigated. (12 refs).
