J/A+AS/127/295      Stark broadening of Kr II lines (Popovic+ 1998)

Stark broadening parameters for Kr II lines from 5s-5p transitions Popovic L.C., Dimitrijevic M.S. <Astron. Astrophys. Suppl. Ser. 127, 295 (1998)> =1998A&AS..127..295P (SIMBAD/NED BibCode)
ADC_Keywords: Atomic physics Keywords: atomic data - line profiles Abstract: With the development of space-borne spectroscopy, spectral line parameters for a large number of lines become of increasing interest for astrophysics. To provide Stark broadening data for ion lines from complex spectra, we present here calculated Stark widths for 37 Kr II lines from the 5s-5p transition. The calculations were performed by using a modified semiempirical approach. The obtained Stark widths are on average in satisfactory agreement with available experimental data. File Summary:
