Electron radiative recombination with a hydrogen-like ion

We survey the results of a long-term study of the process of radiative recombination (RR). A rigorous theory of non-relativistic electron RR with a hydrogen-like ion is used to calculate the total cross section of the process, the effective radiation, the recombination rate coefficient, and the emission coefficient in a plasma with a Maxwellian electron distribution. The exact results are compared with the numerous known asymptotic and interpolation formulas. We propose interpolation formulas which ensure a uniform approximation of all mentioned quantities in a wide range of plasma temperatures.
