Abstract

Pion production by antiproton annihilation on neutron- or proton-rich nuclei is studied in a fully quantum mechanical description of the reaction process in terms of a distorted wave approach. The elementary elastic \(\overline{N} N\) and the \(\overline{N}N\to n\pi\) annihilation vertices are obtained from a t-matrix accounting for coupled channels effects. The theoretical amplitudes are used to derive a microscopic \(\overline{N} A\) optical model potential and the meson production vertices. Nuclear structure effects are taken into account microscopically. Results for meson production cross sections are presented.
