We have investigated Stark line broadening within the spectral series of potassium-like and copper-like emitters, both separately and together. The analysis was performed for fixed values of electronic density N e = 1022 m−3 and temperature |$T = 100\, 000$|  K. Algorithms made for fast data processing also serve for temperature and density normalization of data. Relations obtained using the regularity-based analysis enable predictions of Stark widths for transitions that have not yet been calculated or measured. Results of present investigation can be used for quality control of available Stark width data. [ABSTRACT FROM AUTHOR]

Stark-width dependences on the upper-level ionization potential within different spectral series of neutral lithium have been studied and discussed. Similar dependences have been found for electron- and proton-impact contributions to the Stark widths. The emphasis is on the term structure influence on the studied Stark-width dependences. The effect of series merging with increasing temperature was found. Some lines with deviations from the corresponding series dependences can be explained by the absence of close perturbing states to the transition states. After establishing these dependences, the relations found were used for Stark-width prediction of the missed lines, thus avoiding much more complicated calculation procedures.

ABSTRACT Stark width experimental and theoretical data of neutral helium spectral lines have been used to demonstrate their dependence on the upper-level ionization potential within different spectral series. The emphasis is on the term describing structure influence on the studied Stark-width dependences. After establishing these dependences, predictions were made for electron, proton and ionized helium impact contributions to the Stark widths of neutral helium spectral lines that have not been measured experimentally or calculated theoretically until now (transitions from high levels of He i). The accuracy of the data obtained is comparable with the accuracies of the experimental and theoretical values used in establishing the dependences. [ABSTRACT FROM AUTHOR]
