    "abstract": "We discuss the formation of antihydrogen atoms ($\\bar{\\rm H}$) in an\nultra-cold positron-antiproton plasma. For positron densities $n_p\\agt 10^8$\ncm$^{-3}$ the characteristic formation time of stable $\\bar{H}$ is determined\nby collisional relaxation of highly excited atoms produced in the process of\n3-body Thompson recombination. Relying on the mechanisms of ``replacement\ncollisions\u0027\u0027 and ``transverse collisional drift\u0027\u0027 we find a bottleneck in the\nrelaxation kinetics and analyze the physical consequences of this phenomenon.",
