Theoretical study of dielectronic recombination between electrons and heliumlike carbon ions - art. no. 022715

A revised simplified relativistic configuration-interaction method is used to study the dielectronic recombination processes of He-like carbon ions. E very resonance of type 1s2Lnl has been determined for n = 2,3. The total in tegrated cross sections of the dielectronic recombination are in agreement with the experimental measurements within 10%. It is found that the strong resonance peak around 283 eV consists of three important doubly excited res onance states with the dominant contribution due to two (1s2p P-1) 3d F-2(5 /2,7/2) states, in contrast to the previous assignment of(1s2p P-1) 3p S-2( 1/2) as the dominant resonance state.
