This work reports a theoretical analysis of the Li(2s→2p) photoabsorption spectra when the lithium atoms are evolving in a ground helium buffer gas. The influence of temperature on the far-line wing spectra is particularly examined by adopting classical and full quantum-mechanical approaches. The computations show the appearance, above approximately 1000K, of satellite structures in the blue wing around the wavelength 536nm. The data obtained in the range of temperature 500–3000K agree very well with those already calculated with different theoretical methods.
