RELATIVE INTENSITY OF DIELECTRONIC SATELLITE SPECTRA FOR HIGHLY-CHARGED HE-LIKE IONS (1S2L''NL-1S(2)N'L', N, N'=2, 3) WITH Z=6-54

Relative intensities of dielectronic satellite lines determined by rad iative transition probabilities and autoionization rates have been cal culated for the transitions 1s2l''nl-ls(2)n'l', n, n' = 2, 3 in a wide range of nuclear charge Z. These data together with the wavelengths w ere computed for all satellite lines. Using these data synthetic spect ra could be built for different plasma sources. Perturbation theory me thod has been applied For the calculation of atomic properties of auto ionization states. Correlation, relativistic and radiative effects hav e been taken into account. Factor intensities ed of dielectronic satel lite lines are shown as functions of Z for different types of transiti ons. The Z-dependencies of the ed values have been analysed and very p ronounced sharp peaks have been discovered for this atomic characteris tic indicating that some lines are prominent for specific ionic states and disappear for other ones. A possible explanation for such a behav iour of this atomic characteristic is presented. The resulting theoret ical wavelengths for both satellite lines (1s2l''nl-ls(2)n'l', n, n' = 2, 3) and resonance lines (1snp (13)p(l)-ls(2), n = 2, 3 and 1s2s S-1 3-1s(2)) are compared with available experimental data along isoelectr onic sequences to identify irregularities in the experimental data and to predict wavelengths of ions whose values are unknown or uncertain.
