Résumé

The pressure broadening in the far wings, where the sodium Na (3p 3s) resonance line is perturbed by ground
lithium Li (2s) atoms, has been theoretically analyzed. The NaLi potential–energy curves and the transition dipole moments
are constructed by using a reliable ab initio data points to carry out the reduced-absorption coefficients kr(n,T). This
quantum-mechanical investigation have demonstrated that the NaLi profile spectra show a satellite future in the red wing
at wavelength l = 685 nm in the temperature range 4000 K–1.8104 K. The computation could also exhibit a second
satellite, in the blue wing, near the wavelength l = 574 nm beyond 6000 K and a third peak located at l = 490 nm which
begins to appear at 1.8104 K.
