A new calculation was performed of the dielectronic recombination rate coefficient for the ion, in cases for which static magnetic and electric fields are applied simultaneously in the collision region. The intermediate-state Hamiltonian was diagonal

A theoretical method for determining the effects of static applied electric fields F on the dielectronic recombination (DR) cross section sigma is described. Distorted-wave theory and the isolated resonance approximation are invoked, in an angular mo

The effect on the dielectronic recombination cross section of electric-field-induced mixing of high Rydberg-state (HRS) levels is determined, for both ${\mathrm{Mg}}^{1+}$ and ${\mathrm{Ca}}^{1+}$ target ions. After diagonalizing the energy matrix, $

We review recent progress in understanding of the atomic process known as dielectronic recombination (DR). Currently applied schemes for the calculation of DR cross sections and rate coefficients are described in detail. Methods of dealing with such

The conventional treatment of electron-ion collisions at low energies by the coupled-channel method (CCM) neglects the radiative channels. The effect of radiation is then usually included afterwards perturbatively. For heavy ionic targets, however, t

The dielectronic recombination (DR) rate coefficient ${\ensuremath{\alpha}}^{\mathrm{DR}}$ is explicitly calculated for Mo, Fe, and Ar target ions of the Na isoelectronic sequence (11 electrons). This work is an extension of a previous study of DR fo

Recently, large discrepancies have appeared between theoretical predictions and experimental measurements of dielectronic recombination cross sections (sigma/sup DR/) for Mg/sup 1 +/ targets. This disagreement has provoked new work aimed at understan

The dielectronic recombination cross section is estimated for the system e-+Mg+ in the region of resonance arising from the target excitation 3s to 3p ( Delta nt=0) with capture of the continuum electron into a high Rydberg state (nl). Dominant contr
