J/A+A/542/A75       Stark broadening for the HeI 492.2 line   (Lara+, 2012)

Stark broadening tables for the Helium I 492.2 line. Application to weakly coupled plasmas diagnostics. Lara N., Gonzalez M.A., Gigosos M.A. <Astron. Astrophys. 542, A75 (2012)> =2012A&A...542A..75L
ADC_Keywords: Atomic physics Keywords: line: profiles - atomic data - plasmas - atomic processes Description: The tables contain the area normalized Stark broadened spectral profiles of the HeI 492.2nm line. Doppler effect has not been included in the profiles. The first column of each table is the wavelength detuning, measured in nanometers, from the unperturbed wavelength. The other columns give the spectral profiles for different cases of perturber mass and electron temperature. Each table contains the data for a fixed electron density, ranging from 1020m-3 to 1024m-3 in different tables. Data corresponding to four different reduced masses of the emitter perturber pair, µ, are given in each table. The values of µ given in the tables are µ=0.8, 2.0, 4.0 and 10.0, in units of the proton mass. For each case of µ the profiles for different electron temperatures are given in different columns. Each table has a head giving the electron density value, and the values of µ and temperature corresponding to each column. File Summary:
