Stark Broadening: Hydrogen Lines, Stark Broadening: Plasma
Scientific paper
The generalized theory (GT) of Stark broadening of hydrogen lines in plasmas, published by Ispolatov and Oks (1994) is based on nonperturbative treatment of one component of the electron field. Therefore the GT is intrinsically more accurate than the fully-perturbative, standard theories (ST), such as the theory by Kepple-Griem (1968) (KG) and the theory by Sholin-Demura-Lisitsa (1973) (SDL). The present paper introduces an advanced generalized theory (AGT), that yields closed-form expressions for the width, shift and coupling of Stark states. The authors also present tables of the AGT Stark widths of Lyman and Balmer lines for transitions with upper levels having principal quantum numbers n ≤ 16 and for electron densities from Ne = 1013cm-3 to Ne = 1020cm-3. The mathematical simplicity of the AGT results make it possible to gain physical insight into the important features of the generalized theories that distinguish the AGT/GT from its predecessors.
