Title: | Stark parameter regularities of neutral helium lines within different spectral series | Authors: | Dojčinović, Ivan Tapalaga, Irinel Purić, Jagoš |

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 Hei). The accuracy of the data obtained is comparable with the accuracies of the experimental and theoretical values used in establishing the dependences. © 2011 The Authors Monthly Notices of the Royal Astronomical Society © 2011 RAS. |
