Book excerpt: The effect of external electric fields on the dielectronic recombination cross section associated with the 2s .-->. 2p excitation in the Li like ions B/sup 2 +/, C/sup 3 +/, O/sup 5 +/, and Fe/sup 23 +/, and the 3s .-->. 3p excitation in the Na like ions Mg/sup +/, S/sup 5 +/, Cl/sup 6 +/, and Fe/sup 15 +/ has been studied in the configuration-average, distorted-wave approximation. By applying the linear-Stark approximation to the doubly-excited 2pnl and 3pnl Rydberg states in the presence of an external electric field, we study the systematics of field mixing effects on dielectronic recombination and determine the maximum field enhancement of the dielectronic recombination cross section. We find that the magnitude of the field enhancement decreases as we move up an isoelectronic sequence and is of the order of a factor of two or three in highly-ionized systems. In addition, we show that dielectronic recombination transitions through doubly-excited states near threshold can produce large narrow peaks in the cross section at low energies, which are especially prominent in high stages of ionization, and are not affected by the electric field.

This book was released on 1993 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research program supported by grant DE-FG05-85-ER13394 is to study the properties of autoionizing states to understand in detail dielectronic recombination of ions and electrons. During the period of the present grant, July 1, 1991--June 30, 1994, we have put substantial effort into the study of autoionizing states in Mg. The first topic we have investigated is the angular distribution of electrons ejected from the autoionizing Mg 3pns and 3pnd states. Both of these sets of measurements provide more stringent tests of the K matrix calculations than do measurements of total cross sections. The second topic is the effect of static and microwave electric fields on autoionizing states. Our previous measurements in Ba have shown the profound influence of electric fields on autoionization rates and we have made extensive new measurements in both Ba and Mg. Electric fields are of real importance for dielectronic recombination, since they are present as macroscopic fields in beam experiments and as microfields in plasmas. Finally, we have begun time resolved measurements. We have set up a picosecond laser system, and we have just finished the first experiment with it. Specifically we have used picosecond excitation from a bound Mg 3pnd Rydberg wave packet to the autoionizing 3pnd states to show explicitly the correlation between the spatial location of the Rydberg electron and the frequency of the exciting light.
