Abstract
The pressure broadening in the far wings, where the sodium Na (

. This quantum-mechanical investigation have demonstrated that the NaLi profile spectra show a satellite future in the red wing at wavelength λ =685 nm in the temperature range 4000 K–1.8×104 K. The computation could also exhibit a second satellite, in the blue wing, near the wavelength λ =574 nm beyond 6000 K and a third peak located at λ =490 nm which begins to appear at 1.8×104 K.
