PRECISE MEASUREMENTS AND THEORETICAL CALCULATIONS OF HE-LIKE ION RESONANCE LINE SATELLITES RADIATED FROM BE-LIKE, B-LIKE, C-LIKE, N-LIKE, O-LIKE, AND F-LIKE IONS

Spectra with spectral resolution lambda/DELTAlambda congruent-to 3000-7000 in the vicinity of the He-like ion resonance lines Mg, Al, Si, P, S were obtained in CO2 laser-produced plasma. The wavelengths of these satellites were measured and compared with numerical calculations. Identification of lines or a group of overlapping lines was performed. Twenty-two transitions of dielectronic satellites for Be-like ions, 41 transitions for B-like, 40 transitions for C-like, 22 transitions for N-like, 12 transitions for O-like ions and 2 transitions for F-like ions were identified. The average between theoretical and experimental wavelengths was +/-(0.0005-0.001)angstrom, but in some cases it was +/-(0.002-0.003)angstrom.
