Observation in laser plasmas and identification of dielectron satellites of spectral lines of hydrogen- and helium-like ions of elements in the Na–V range

The results are given of the observations, in the 2–19-A wavelength range, of spectral lines emitted from laser plasmas of hydrogen- and helium-like ions of Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, and V (Z = 11–23, ionization potentials up to 6.86 keV). Transitions of the n l n' l' – 1s n' l' and 1s 2p n l – 1s2 n l type in helium- and lithium-like ions, respectively, are identified. A total of 180 lines are described and identified. The precision of the wavelength measurements is 0.002 A at λ ≈ 10 A and 0.0005 A at λ ≈ 2.5 A. The results obtained are combined with the results of published laboratory and astrophysical investigations in a review table.
