Absorption Measurements of the Principle Series Lines of Cs Broadened by Xe

Joachim Lorenzen, Kay Niemax

Abstract The absorption coefficients of the statistical wings of the Cs principal series lines 6 2S1/2 - n 2P3/2 (6 ≦ n ≦ 10) and 6 2S1/2 - n 2P1/2 (6 ≦ n ≦ 9) perturbed by Xe have been measured quantitatively The results are compared with quasistatic line wings calculated from the interatomic Cs -Xe potentials of Baylis 1 and Pascale and Vandeplanque 2. In the far wings of the higher lines of the series indications of many-body interaction were found. Furthermore the behaviour of the shift of all principal series lines up to the 23rd member was investigated in the density region between 1.63 X 1018 and 1.9 X 1019 Xe atoms per cm-3.Abstract The absorption coefficients of the statistical wings of the Cs principal series lines 6 2S1/2 - n 2P3/2 (6 ≦ n ≦ 10) and 6 2S1/2 - n 2P1/2 (6 ≦ n ≦ 9) perturbed by Xe have been measured quantitatively The results are compared with quasistatic line wings calculated from the interatomic Cs -Xe potentials of Baylis 1 and Pascale and Vandeplanque 2.

Line-broadening studies of excited diatomic homoatomic and heteroatomic Rydberg molecules formed by potassium, rubidium, and cesium atoms

Cedomil Vadla, Vlasta Horvatić, Kay Niemax

Recent absorption measurements of the self-broadening of Rb principal series lines [C. H. Greene, E. L. Hamilton, H. Crowell, C. Vadla, and K. Niemax, Phys. Rev. Lett. 97, 233002 (2006)] verified the existence of minima in highly excited long-range potentials of ${\text{Rb}}_{2}$ which were predicted theoretically as bound Rydberg molecule [C. H. Greene, A. S. Dickinson, and H. R. Sadeghpour, Phys. Rev. Lett. 85, 2458 (2000)]. The present paper reports on the extension of these experimental studies to principal series lines of K broadened by K as well as Cs broadened by Cs. In addition, the broadening of some lower members of the K, Rb, and Cs principal line series due to heteroatomic interactions was investigated. The analysis of the measured satellite structures in the quasistatic line wings and their comparison to the previously published analogous data for ${\text{Rb}}^{\ensuremath{\ast}}+\text{Rb}$ system lead to the conclusion that one can expect existence of potential minima in homo- and heteroatomic alkali-metal ${A}^{\ensuremath{\ast}}+B$ systems in a wide range of principal quantum numbers, starting with K, Rb, and Cs excited to the third resonance states. The positions and strengths of the satellite structures indicate that the potential minima are due to scattering of the valence electron by ground-state perturbers.Recent absorption measurements of the self-broadening of Rb principal series lines [C.
