Antiproton–hydrogen and antihydrogen–hydrogen annihilation at sub‐Kelvin temperatures
Abstract The main properties of the interaction of ultra low‐energy antiprotons (E⩽$ 10^{-6} $ a.u.) and antihydrogen with atomic hydrogen are established. Elastic and inelastic cross‐sections and Protonium formation spectrum are calculated within quantum mechanical coupled channels approach. The re...

520 | |a Abstract The main properties of the interaction of ultra low‐energy antiprotons (E⩽$ 10^{-6} $ a.u.) and antihydrogen with atomic hydrogen are established. Elastic and inelastic cross‐sections and Protonium formation spectrum are calculated within quantum mechanical coupled channels approach. The results of calculations differ strongly from predictions made by extrapolation of semiclassical models to the energy domain of interest. It is shown that the main feature of the observables behaviour is determined by existence of a family of $${\bar p}$$H, $${\bar H}$$H near‐threshold metastable states. | ||

Antiproton–hydrogen and antihydrogen–hydrogen annihilation at sub‐Kelvin temperatures |
abstract |
Abstract The main properties of the interaction of ultra low‐energy antiprotons (E⩽$ 10^{-6} $ a.u.) and antihydrogen with atomic hydrogen are established. Elastic and inelastic cross‐sections and Protonium formation spectrum are calculated within quantum mechanical coupled channels approach. The results of calculations differ strongly from predictions made by extrapolation of semiclassical models to the energy domain of interest. It is shown that the main feature of the observables behaviour is determined by existence of a family of $${\bar p}$$H, $${\bar H}$$H near‐threshold metastable states. © Kluwer Academic Publishers 1998 |
