Abstract

Cross sections of ultra low-energy antiprotons (E ≤ 10-6 a.u.) and antihydrogen with atomic hydrogen are calculated within a quantum mechanical coupled channels approach. The results differs from the extrapolations of semiclassical models. The main features of the observables are found to be determined by a family of pH, HH nearthreshold metastable states.
