X-ray wavelengths and Auger transition energies of 1s 2p4 (2S, 2,4P, 2D) resonance in B-like (Z = 6-18) ions

We report Auger energies of the 1s 2p4 (2S, 2,4P, 2D) resonances belonging to the 1s 2p4 (2S, 2,4P, 2D)?1s2 2p2 (1S, 1P, 1D) and to the 1s 2p4 (2S, 2,4P, 2D)?1s2 2s2p 1,3P transitions in B-like ions (Z=6–18). X-ray wavelengths of the 1s2p4 (2S, 2P, 2D) 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 2p4 (2S, 2,4P, 2D) resonances in B-like C+,O3+, Ne5+, Mg7+ and Si9+ 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 2p4 (2S, 2,4P, 2D) resonances in B-like N2+,F4+, Na6+, Al8+,P10+,S11+, Cl12+ and Ar13+ 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.
