论文摘要
我们提出了有关对应原理的问题，描述了相对充满电的颗粒的重组。这些问题来自宇宙暗物质（DM）问题调查。考虑具有库仑状相互作用的颗粒。尽管问题似乎更为笼统，但假定DM颗粒之间的这种类似库仑的相互作用。分析表明，不同半经典方法的使用导致重组数量数量之间的明显差异。我们试图找到某些条件，在哪些经典横截面（与多个软光子过程有关的经典横截面）还原为量子一个条件下，这是在半古典近似（Kramers's公式）中获得的。我们只是提请注意这一点，并提供一些（不是决定性的）论点。
We raise the issues concerning correspondence principle in description of a recombination of oppositely charged particles. These issues have come from cosmological dark matter (DM) problem investigations. Particles possessing Coulomb-like interaction are considered. Such Coulomb-like interaction between DM particles is assumed though the problem seems to be more general. Analysis showed that usage of different semiclassical approaches leads to the apparent discrepancy between numbers of recombination acts. We attempted to find some conditions under which classical cross-section (which relates to multiple soft photon process) reduces to quantum one, which is obtained in semi-classical approximation (Kramers' formula). We just draw attention to this and provide some (not decisive) arguments.
