Abstract

A physical model is proposed, which makes it possible to determine the velocity distributions of antihydrogen atoms formed as a result of three-body recombination for the given parameters of an antiproton–positron plasma. Particle velocity relaxation is accounted for using the Derbenev–Skrinskii approach. The recombination rate is calibrated from the available results of molecular dynamics calculations. Good agreement with experimental results is achieved. The model makes it possible to estimate the efficiency of trapping of atoms in experimental conditions for obtaining antihydrogen.
