Recently, we demonstrated that the enhancement of dielectronic recombination by an electric field, or crossed electric and magnetic fields, may be reduced 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 remained as to how these predicted reductions might be affected when one removes the degeneracy inherent in the CA approximation and includes the interactions between the resonant states associated with individual intermediate-coupled levels. In the present paper we address that issue for the case of dielectronic recombination in the presence of an electric field. Indeed we have found that these more detailed calculations support the general conclusions of our earlier work and provide additional insight into the effects of interacting resonances on dielectronic recombination in the presence of fields. Results for the Li-like ions C3+, Ne7+, and Si11+ are presented.
