Abstract
An analysis, based on the quantum mechanical impact theory, is made of the electron-produced width and shift of the 2l2l' dielectronic satellite lines. In particular, the screening effects of the spectator electron on the dielectronic lineshift are investigated and discussed in connection with the parent lineshift. Numerical calculation has been carried out for the line parameters of the two helium-like transitions (2p2)1D to (1s2p)1P and (2s2p)1P to (1s2s)1S in laser plasmas. It is shown that the perturbation effects in the upper and lower levels of these transitions are of equal importance and also that the inelastic cross section contribution in line broadening completely masks the elastic one.Keywords
