The dc-field-induced interference effects in recombination in a model system consisting of two close-lying autoionizing states are studied. The two states are strongly coupled by a dc field and can decay via both autoionization and spontaneous emission. All possible channels of radiative decay are included for the model system. In special cases the isomorphism of the recombination and photoionization studies is established. The total integrated recombination probability is calculated and its behavior as a function of dc field is presented. Our density-matrix calculations lead to the known results in the limiting case of no dc field.
