Sodium 3s-3p far wing shapes induced by ground neon atoms

This study deals with the broadening of atomic sodium, evolving in a neon buffer gas, in the wavelength and temperature ranges 500--700nm500--700nm and 136--3000K136--3000K, respectively. The computed emission and absorption spectral profiles are based on the most recent potential energy curves and transition dipole moments. The required electronic Na(S-2) +Ne(S-1)+ and Na(P-2)+Ne(S-1) potentials are used from two different sets. Then the satellite structures in the blue wing are analysed quantum mechanically. The calculations show especially that the free-free transitions contribute most to the NaNe photoabsorption spectra and a satellite structure is observable beyond the temperature 402K402K around the wavelengths 550nm550nm depending on the used potential set. The obtained results showed good agreement with those already published.
