Predicted alkali collision broadening by noble gases based on semiempirical potentials

The collision broadening and shift of lithium, sodium, potassium, rubidium and caesium principal series lines by helium, neon, argon, krypton and xenon perturbers is tabulated based on the impact approximation and semiempirical interatomic potentials. Comparisons are made with available experimental data. The temperature dependence of the line broadening and shift rates is also estimated.
