A theoretical calculation is presented for absorption-line profiles of alkali-metal atomic spectra. The red- and violet-satellite bands caused by interactions with noble-gas perturbing atoms are discussed in detail. The statistical theory is used in calculating absorption profiles. It is shown that the pair-distribution function between atoms has an important, and temperature-dependent, influence on the red-satellite bands.

Photon echoes have been employed to measure the relative broadening rates of the lithium $D$ lines perturbed by the noble gases. We find that, for each noble-gas perturber, the ${D}_{1}$ -line and ${D}_{2}$ -line photon-echo-relaxation rates are identical. Our results are compared with those obtained in line-shape studies of pressure broadening.Photon echoes have been employed to measure the relative broadening rates of the lithium $D$ lines perturbed by the noble gases.
