Title: | Stark width regularities within neutral calcium spectral series | Authors: | Tapalaga, I. Dojčinović, Ivan Milosavljevi, M. K. Purić, Jagoš |
Keywords: | atomic data;line: profiles;opacity;plasmas;radiative transfer | Issue Date: | 19-Mar-2012 | Journal: | Publications of the Astronomical Society of Australia | Abstract: | Dependences of electron and proton impact Stark width on the upper level ionization potential within different series of the neutral calcium spectral lines have been evaluated and discussed. The similar dependences previously found for the electron impact contribution were also obtained for the proton impact contribution to the Stark broadening. The emphasis is on the term structure influence on the studied Stark width dependences. The influence of the lower transition level and transition term is higher at low temperatures. After establishing these dependences, predictions were made for Stark widths of neutral calcium spectral lines not measured experimentally or calculated theoretically until now. 2012 Astronomical Society of Australia. |
