Inner-shell excitation energy and autoionization rates for Li-, Be-, B-like ions with Z = 6–54

Abstract

Absolute energies of the autoionization states 1s2s22pn [LSJ] with n = 0–2, 1s2s2pn [LSJ] with n = 1–3 and 1s2pn [LSJ] with n = 2–4 and non-autoionizing states 1s22s22pn [LSJ] with n = 0–1, 1s22s2pn [LSJ] with n = 0–2 and 1s22pn [LSJ] with n = 1–3 were calculated for ions with nuclear charge Z = 6–54 by using the 1/Z perturbation theory method. Relativistic corrections were taken into account in the frame of the Breit operators. The autoionization rates for the above-mentioned autoionization states for ions with Z = 6–54 were computed as well. These data are very important for modelling the satellite spectra produced by high-temperature plasma with thermal and non-thermal electrons.
