Intermediate-coupling calculations of the effects of interacting resonances on dielectronic recombination in a static electric field

Recently, we demonstrated that the enhancement of dielectronic recombinatio n by an electric field, or crossed electric and magnetic fields, may be red uced by the interaction between resonances through a common continuum [Phys . Rev. Lett. 80, 1402 (1998)]. However, these calculations were carried out in a configuration-average (CA) approximation and the question then remain ed as to how these predicted reductions might be affected when one removes the degeneracy inherent in the CA approximation and includes the interactio ns between the resonant states associated with individual intermediate-coup led levels. In the present paper we address that issue for the case of diel ectronic recombination in the presence of an electric field. Indeed we have found that these more detailed calculations support the general conclusion s of our earlier work and provide additional insight into the effects of in teracting resonances on dielectronic recombination in the presence of field s. Results for the Li-Like ions C3+, Ne7+, and Si11+ are presented. [S1050- 2947(98)02712-7].
