Chemical reaction of negative particles p̄, K−, and μ− with molecular ions

Rearrangement processes of the exotic system, X− + H2+ → X−p + H, where X−=p̄ (antiproton), K− (negative kaon), and μ− (negative muon), can be treated as a familiar type of chemical reaction, i.e., collisions on a single Born–Oppenheimer potential energy surface. The cross-section for this reaction and the state distribution of the formed exotic atoms X−p are calculated by the classical trajectory Monte Carlo method. The reaction dynamics is investigated by comparison with the X− + H and H2 systems.
