Recently as a result of more active research on dense high temperature plasmas prominent importance has been acquired by the development of the theory of Stark broadening of multi-charged ions spectral lines (SL). This theory muat take into account, on the one hand, the presence of fine structures in ion energy levels, and on the other hand, the effects appearing in the dense plasma : (1) dipole as well as quadrupole interaction with plasma ion microfield ; (2) plasma polarization ehift (PPS) of SL due to the mean electric field where the ion emitter is situated. Over the recent years a number of papers has appeared [1-4] which consider different aspects of the theory for ions with one and with two electrons.
