Collision Broadening and Shift of Cesium D₂Resonance Line Perturbed by Every Rare Gas

Pressure shifts and broadening of the Cs D1 and D2 lines by He, N2, and Xe at densities used for optical pumping and spin exchange polarization

“…17,26 The Cs D 1 and D 2 shifts and widths determined in the present work are summarized in Table I, which also includes the previous measurements taken at low pressures ͑Ͻ0.25 amagat͒ of 4 He and N 2 by Andalkar and Warrington 18 and of Xe by Inoue et al 20 The line shift and broadening parameters of Andalkar and Warrington and Inoue et al are smaller across the board than those reported in this work, and the differences between the measurements are FIG. This distortion makes the FWHM an ill-defined quantity for densities greater than 2 amagat.…”

“…Cesium pressure shifts and broadening have been reported at room temperature and very low pressures of a few hundred torrs, [18][19][20] but extrapolation of these results to pressures of many atmospheres and higher temperatures typically used for SEOP may not be appropriate. In fact, our early efforts to use these literature values to calculate the D 1 absorption resonance in our Cs SEOP system resulted in noticeable discrepancies between the calculated and measured resonances.…”

Spectral dependence of polarization of cesium atoms during pumping by a narrowband semiconductor laser

“…The constants of broadening and shift of the D 2 line of Cs in helium (29.4 and 0.73 MHz/Torr) were taken from paper [7]. The calculation was carried out for the power of laser pumping light of 3 μW, which was used in experiment.…”

Spectroscopy of alkali-metal atoms in dense supercritical4He at low temperatures

“…8, we show the values of γ /ρ 0 obtained from Eq. (1) as a function of the absolute temperature and compare them with high-temperature experimental data available in the literature [8,[27][28][29][30][31].…”
