The binding energies of antihydrogen atoms formed when antiprotons are mixed with positron plasmas having densities ranging from 10¹³–10¹⁵m⁻³, and at temperatures of 5–30K, have been investigated using simulations. Major changes in the distribution of binding energies are observed, with more strongly bound states evident at the higher densities, and at lower temperatures. For deeper binding, the distribution of binding energies follows a power-law which is found to be strongly dependent upon plasma properties and the strength of the applied magnetic field. The underpinning role of collisions in determining the binding energies is explored.

冷质正电子等离子体中反质子相互作用形成的氢的结合能

使用模拟研究了将质子与密度为10 ¹³ –10 ¹⁵ m ^-3且温度为5–30K的正电子等离子体混合时形成的氢原子的结合能。观察到结合能分布的主要变化，在更高的密度和更低的温度下，结合力更强的状态更加明显。对于更深的结合，结合能的分布遵循幂律，该幂律被发现强烈依赖于等离子体特性和所施加磁场的强度。探索了碰撞在确定结合能中的基础作用。
