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.

强磁场中反质子和正电子的弛豫和复合

摘要

提出了一个物理模型，对于给定的质子-正电子等离子体参数，可以确定由于三体重组而形成的反氢原子的速度分布。使用Derbenev–Skrinskii方法解释了粒子速度松弛。重组率是根据分子动力学计算的可用结果进行校准的。与实验结果良好吻合。该模型可以估算在获得反氢的实验条件下原子的捕集效率。
