Spectra for electric-dipole Δn = 0 transitions in highly ionized sulfur ions

Spectra for Δn = 0 transitions of the type 2s22pk-2s2pk+1 or 2s2pk-2pk+1 from highly ionized sulfur produced in beam-foil excitation are investigated and compared to similar spectra measured with other types of light sources. In the experiment, fifty lines have been identified, of which eleven lines are new and accurately measured. Analysis of spectra was based on comparisons with other experimental results and calculated values.
