Radiative Recombination Rate Coefficients

Radiative recombination rate coefficients obtained using the nonrelativistic dipole result of Stobbe for the RR cross section are compared to other nonrelativistic approaches. A good agreement is found with widely used formulas. The RR rate coefficients can be calculated for different beam temperatures and for arbitrary nl sublevels up to high Rydberg states. The computation technique used allows us a fast evaluation of the dipole matrix elements without any additional approximation.
