A quantum-mechanical solution to the problem of radiative recombination of an electron in the Coulomb field has long been known. However, in astrophysics, the classical approach is sometimes used to describe similar processes in systems of magnetic monopoles or interacting dark matter particles. The importance of such problems is determined by the fact that recombination processes play a decisive role in the evolution of the large-scale structure of the Universe. It is shown that the applicability of the quantum and classical approaches to radiative recombination is closely related to the magnitude of the radiated angular momentum and its quantization. For situations where the classical approach is not suitable, a semiclassical approach based on consideration of the quantization of the angular momentum is proposed. It can be useful for an approximate description of radiative recombination in a variety of systems.
