Abstract
The aim of this work is to investigate the Stark shifts of some hydrogenic atoms and ions in hot dense plasmas. For this, Debye-Hückel (DH) and Ion-Sphere (IS) potential are used to estimate Hα(HI) and Pα(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 Hα and more than 40 measurements for Pα 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 (1017 − 3 × 1019) cm−3.
