Pressure Effects of Foreign Gases on the Absorption Lines of Cesium. V. The Effects of Xenon and CF4

The shift, broadening, and asymmetry of the doublet components of the first member of the Cs principal series produced by various relative densities of Xe up to 47 are described. The shift of 17 other high-member doublets is also reported for Xe up to a relative density (rd) of 5. The effects due to Xe are very similar to those due to Kr. The shift, broadening, and asymmetry curves for Xe, although much more pronounced, have the same qualitative shape as our recently reported curves for Ar and Kr. The observed half-widths of various Cs lines produced by C${\mathrm{F}}_4$ are very similar to those produced by Xe, and the red shifts are close to those produced by Kr and Xe.
