Li(2p ← 2s) + Na(3s) pressure broadening in the far-wing and line-core profiles

Abstract

This work reports pressure-broadening line-wing and line-core of the lithium Li (2p ← 2s) resonance line perturbed by ground sodium Na (3s) atoms. In far-wing region the calculations are performed quantum-mechanically and are intended to examine the photoabsorption coefficients at diverse temperatures. The results show the existence of three satellites, in the blue wing near the wavelengths 470nm and in the red wing around 862 and 1070nm. For the line-core region, by adopting the simplified Baranger model the line-width and line-shift rates are determined and their variation law with temperature is examined. No published data were found to compare these results with.
