摘要：

The aim of this work is to investigate the Stark shifts of some hydrogenic atoms and ions in hot dense plasmas. For this, Debye-Huckel (DH) and Ion-Sphere (IS) potential are used to estimate H-alpha(HI) and P-alpha(HeII) line shift. These calculations have been implemented through self-consistent methods by using atomic structure code AUTOSTRUCTURE. These results have been compared with 50 experimental data for H-alpha and more than 40 measurements for P-alpha obtained by different authors. The main conclusion is that a self-consistent calculation with the Ion-Sphereperturbing potential fairly well describes the shifts of hydrogenic ions in plasmas for electron density in the range (10(17) - 3 x 10(19)) cm(-3).
