Theoretical studies of dielectronic recombination and resonant transfer excitation for highly ionized Cu18+ ions
高离化态Cu18+离子的双电子复合及共振转移激发过程的理论研究

The dielectronic recombination cross sections of Cu18+ ions are calculated using a quasi-relativistic theory. The effects of configuration interaction to the cross sections are analysed. Base on the calculated data, the resonant transfer excitation cross sections of Cu18+ with H2 targets are estimated by using the convolution of Compton profile of the target electron in the impulse approximation. Good agreement of the present calculation with new experimental observation is achieved.
