Abstract
Annihilation cross-section of ultra low-energy atomic antihydrogen (E less than or equal to 10(-5) a.u.) on atomic hydrogen are calculated within a qu antum mechanical coupled channels approach. The results differ from the ext rapolations of semiclassical models to low energies. The main features of t he observables are found to be determined by a family of H (H) over bar nea rthreshold metastable states.
