Abstract [en]

We consider the hyperfine transitions in ultracold collisions of  hydrogen (H) and antihydrogen ((H) over bar) atoms. The cross sections for transitions between various spin states are calculated. We show that hyperfine transitions in (H) over bar -H collisions are basically driven by the strong force between proton and antiproton.
