Abstract:
A Simplified Relativistic Configuration Interaction (SRCI) method is used to calculate the dielectronic recombination rate coefficients to the excited states of He from He^+. In this method, the infinite resonant doubly excited states involving high Rydberg states are treated conveniently in a unified mannar by interpolation. The dielectronic recombination processes for DeltaN = I and DeltaN = 2 transitions are included in our calculations, and the cross sections are in agreements with the experimental measurements. The rate coefficients to the excited states are fitted to an analytical formula and the n-dependences of the fitting parameters are discussed.
