The Ion Line Stark Parameters Dependence on the Emitter Rest Core Charge and the Electron Temperature within Ns-Np Transition Arrays

Abstract

Recently published Stark widths and shifts measured and calculated data and their dependence on the upper level ionization potential χ are used here to demonstrate the existence of the other kinds of reularities within similar spectra of different elements and their ionization stage. The emphasis is on the Stark parameter dependence on the rest core charge and the electron temperatures for the lines from similar spectra. The found relations connecting Stark broadening and shift parameters and upper level ionization potential, rest core charge and electron temperature were used for a prediction of new Stark broadening data, avoiding much more comlicated procedures. For opacity calculations and investigation of stellar atmosphere, when a large number of line broadening data was required, present investigation are useful in enlarging the number of required data. This field of research remains largely open to other demonstrations of regularities and similarities, as long as one can relate the same kind of spectroscopic transition. Also, the attained dependencies can be used as an additional criteria for checking accuracy of the particular theoretical and experimental data from diferent sources.
