CALCULATION OF DIELECTRONIC RECOMBINATION CROSS-SECTIONS AND RATE COEFFICIENTS FOR HELIUM-LIKE CARBON

A simplified relativistic configuration interaction method is used to calculate the dielectronic recombination cross sections and rate coeff icients for heliumlike carbon. In this method, the infinite resonant d oubly excited states can be treated conveniently in the frame of Quant um Defect Theory. Our calculated cross sections are in agreements with the experimental measurements except for the 1s2lnl'(n = 6,7) resonan ces. The total energy-integrated cross sections and rate coefficients over all dielectronic resonances are in agreements with the experiment al measurements within 10% percent.
