Stark broadening data for spectral lines of rare-earth elements: Nb III
arXiv:1311.1948 · doi:10.1016/j.asr.2013.11.025
Abstract
The electron-impact widths for 15 doubly charged Nb ion lines have been theoretically determined by using the modified semiempirical method. Using the obtained results, we considered the influence of the electron-impact mechanism on line shapes in spectra of chemically peculiar stars and white dwarfs.
