Abstract
Atom-antiatom rearrangement collisions in which the nucleus-antinucleus bound state is formed are important processes in atom-antiatom interactions. We give a general discussion of the atom-antiatom interatomic potential energy and calculate for H-, -H, and -Ar where means antimuonium ( atom). We apply the semiclassical and optical-potential methods to determine cross sections for rearrangement collisions. At low energies these collisions are the dominant processes leading to particle-antiparticle annihilation.
