The effects of external electric fields on dielectronic recombination have been studied in the distorted-wave approximation. The eigenvectors for the doubly excited Rydberg states were determined by diagonalizing a Hamiltonian matrix which includes the internal electrostatic and spin-orbit terms, as well as the Stark matrix elements. Calculations were performed for the dielectronic recombination transitions associated with the 2s..-->..2p excitation in the Li-like ions B/sup 2 +/, C/sup 3 +/, and O/sup 5 +/; and the 3s..-->..3p excitation in the Na-like ions P/sup 4 +/, S/sup 5 +/, and Cl/sup 6 +/. The results for the Na-like ions are compared with recent merged-beam measurements, and the differences between the two sequences with respect to the enhancement of dielectronic recombination as a function of electric field strength are discussed.
