摘要：

We discuss the formation of antihydrogen atoms ((H) over bar) in an ultra-cold positron-antiproton plasma. For positron densities n(p) greater than or similar to 10(8) cm(-3) the characteristic formation time of stable (H) over bar is determined by collisional relaxation of highly excited atoms produced in the process of three-body Thompson recombination. Considering on the mechanisms of ''replacement collisions'' and ''transverse collisional drift'' we find a bottleneck in the relaxation kinetics and analyze the physical consequences of this phenomenon.
