    ABSTRACT: We report on multiconfiguration Breit-Pauli calculations for the photorecombination of Ti4+ ions. Through a detailed comparison with the Test Storage Ring measurements of Schippers et al., we quantify the interference effects for the broad, asymmetric, near-threshold, highly correlated 3p53d2(2F) resonances. We also discuss the enhanced field ionization effects on recombined 3p6nl Rydberg states. This is due to the perturbation of the below-threshold tails of two of the broad 3p53d2(2F) resonances, giving rise to a “forced autoionization” phenomenon, increasing the field ionization effects. By accounting for interference for the lowest n=3,4 resonances, and field effects as n→∞, excellent agreement between our computed results and the experimental photorecombination spectrum is obtained. ========================================= CITED IN: --------------------------------------------- ELECTRON-ION RECOMBINATION OF Mg6 + FORMING Mg5 + AND OF Mg7 + FORMING Mg6 +: LABORATORY MEASUREMENTS AND THEORETICAL CALCULATIONS M.
