Abstract

Abstract: We report Auger energies of the 1s 2p 4 ( 2 S, 2, 4 P, 2 D) resonances belonging to the 1s 2p 4 ( 2 S, 2, 4 P, 2 D) → 1s 2 2p 2 ( 1 S, 1 P, 1 D) and to the 1s 2p 4 ( 2 S, 2, 4 P, 2 D) → 1s 2 2s2p 1, 3 P transitions in B-like ions (Z = 6–18). X-ray wavelengths of the 1s2p 4 ( 2 S, 2 P, 2 D) resonances are also reported. The calculations are carried out in the framework of the screening constant by unit nuclear charge (SCUNC) formalism. The present results for the core-excited 1s 2p 4 ( 2 S, 2, 4 P, 2 D) resonances in B-like C +, O 3+, Ne 5+, Mg 7+ and Si 9+ ions agree well with recent saddle-point variation and saddle-point complex-rotation (SPCR) results (Sun et al 2013 Phys. Rev A 87 032509 ). The new Auger energies and wavelengths for the 1s 2p 4 ( 2 S, 2, 4 P, 2 D) resonances in B-like N 2+, F 4+, Na 6+, Al 8+, P 10+, S 11+, Cl 12+ and Ar 13+ ions provide benchmarked values for future experimental and theoretical studies on these B-like ions in connection with the diagnostic of astrophysical and laboratory plasma.
