Bonn meson-exchange potential in theN-N¯system

Abstract
A G-parity transformation is performed on the latest version of the Bonn N-N meson-exchange potential to derive the elastic part of the N- interaction. No additional modification of the intermediate- and short-range domain is introduced. A phenomenological complex potential of Gaussian form is added to account for N- annihilation. A good description of low- and intermediate-energy N- data is achieved. The relevance of isobar degrees of freedom in the elastic N- interaction is discussed.
