Relativistic many-body calculations of dielectronic satellite spectra created by autoionizing 1s2l2l′ states in Li-like ions

摘要

Relativistic many-body perturbation theory, including the Breit interaction, is used to evaluate energy levels, radiative matrix elements and autoionization rates for 1s2l2l′ states of lithium-like Mo~(39 +), Pr~(56 +), W~(71 +) and Hg~(77 +). Radiative and non-radiative data are combined to obtain branching ratios, intensities and effective emission rate coefficients of dielectronic satellite lines. Relative intensity factors are shown graphically for the 1s2l′2l″-1s ~22l radiative transitions in lithium-like ions with nuclear charges Z ranging from 6 to 100; however, our emphasis here is on dielectronic recombination rates in the four lithium-like ions listed above. Such data, for high-Z ions in particular, are relevant to spectroscopic diagnostics of very high-temperature plasmas including future experiments at the International Thermonuclear Experimental Reactor.
