Abstract
Recent experimental hints of the existence of nucleon-antinucleon quasi-bound states are presented and discussed. One, very broad and weakly bound S wave state is indicated in two decay modes of the J/Ψ meson. It finds additional support in the level widths measured in light antiprotonic atoms. Another, a narrow P-wave state, is found instrumental in the understanding of several results obtained in heavy antiprotonic atoms. Both states have a natural explanation in a fairly traditional Paris potential model of the NN̄ interactions.
