INTERACTION OF NUCLEONS WITH ANTI-NUCLEONS .1. GENERAL FEATURES OF THE NBARN SPECTRUM IN POTENTIAL MODELS

We discuss the general features of the spectrum of antinucleon-nucleon (NN bound states and resonances, using real potentials obtained via G-parity transformation from several realistic NN models. The main properties of the NN level ordering emerge from a model independent study of the coherences of meson exchange forces, which are complementary to those characterizing the NN system. However, the absolute energies of NN states, and the level density near threshold are very model dependent. © 1979.
