Intensities of resonance line satellites of helium-like ions with Z = 12–23 in laser plasma x-ray emission

A detailed comparison was made between the experimental and theoretical relative intensities of the satellites to check the calculations of the probabilities of radiative decay A_s and autoionization Γ_s of doubly excited states, and of the ratio between the rates of excitation of an electron from the K shell of a lithium-like ion and of the resonance line C ^k_s/C_R. This analysis of the intensities of the resonance line satellites of multiply charged helium-like ions with Z=12–23 showed good agreement between theory and experiment. From this it was concluded that the calculations of the decay probabilities and excitation cross sections of the autoionized levels were reliable and could be used to develop diagnostic techniques for dense high-temperature laser plasmas.
