当反质子与密度范围为1013-1015 m−3的正电子等离子体混合时，在5-30 K的温度下形成的反氢原子的结合能已经被模拟研究。结合能分布的主要变化，观察到，更强烈的束缚态明显在较高的密度，并在较低的温度下。对于更深的结合，结合能的分布遵循幂律，这被发现是强烈依赖于等离子体的性质和所施加的磁场的强度。碰撞在确定结合能的基础作用进行了探讨。
The binding energies of antihydrogen atoms formed when antiprotons are mixed with positron plasmas having densities ranging from 1013–1015 m−3, and at temperatures of 5–30 K, 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.
