Title: Hydrogen-Antihydrogen Collisions

Abstract

Matter-antimatter interactions are investigated using hydrogen-antihydrogen collisions as an example. Cross sections for elastic scattering and for the antihydrogen loss (either through the rearrangement reaction, resulting in formation of protonium and positronium according to H+H(bar sign){yields}p p(bar sign)+e{sup +}e{sup -} , or via annihilation in flight) are calculated for the first time in a fully quantum mechanical approach. Implications for experiments intending to trap and cool antihydrogen are discussed. (c) 2000 The American Physical Society.
