Radiative recombination rate coefficients

Radiative recombination rate coefficients obtained using the nonrelativisti c dipole result of Stobbe for the RR cross section are compared to other no nrelativistic approaches. A good agreement is found with widely used formul as. The RR rate coefficients can be calculated for different beam temperatu res and for arbitrary nl sublevels up to high Rydberg states. The computati on technique used allows us a fast evaluation of the dipole matrix elements without any additional approximation.
