Inner-shell Excitation Energies and Autoionization Rates for C-, N-, O-, and F-like Ions with Z = 6–54

Abstract

Absolute energies of the autoionizing states 1s2s22pn [LSJ] with n = 3–6, 1s2s2pn [LSJ] with n = 4–6 and 1s2pn [LSJ] with n = 5–6, and non-autoionizing states 1s22s2pn [LSJ] with n = 2–6, 1s22s2pn [LSJ] with n = 3–6, and 1s22pn [LSJ] with n = 4–6 were calculated for ions with a nuclear charge Z = 6–54 by using the 1/Z perturbation theory method. These states were considered as the states with one or few holes in the Ne-like core state 1s22s22p6. Relativistic corrections were taken into account in the frame of the Breit operators. The autoionization rates for the above-mentioned autoionizing states and ions were computed as well and are shown in grafic forms as Z-dependences. These new atomic data represent an important material, which can be used in different areas of atomic and plasma physics involving the study of multiply-charged ions.
