Stark broadening along a homologous sequence of noble gas atomic lines in dense plasmas
Abstract
The authors present experimental results on the broadening and shift of some rare gas atomic lines emitted by high electron density plasmas created in linear flashtubes. From a semi-empirical formula, they find a theoretical dependence of the Stark broadening parameters on the ionisation potential for lines broadened by electron impacts. Experimentally, a non-linear dependence is found between the Stark width w and shift d, and the electron density. At the lowest electron density, the authors' values of w and d agree with other experimental determinations. The authors have observed a regularity of w and d for analogous lines of homologous atoms.
