We experimentally investigate trap-loss spectra of the cesium 6S 1/2 (F = 4) → 71P 3/2 Rydberg transition by combining the cesium atomic magneto-optical trap with the narrow-linewidth, continuously tunable 318.6 nm ultraviolet laser. Specifically, the atoms in the magneto-optical trap are excited to the Rydberg state due to the ultraviolet laser …

The vapor pressures of high-purity cesium, rubidium, and NaK (sodium-- potassium alloy) of 30.6 wt % sodium were measured from roughly 1 to 100 lb psi abs. The method employed boiling under argon, in a small capsule to ensure temperature uniformity. Recent independert results by others on sodium, in close agreement with earlier sodium data …

II.A.4 Cesiated Surfaces. Thus far, all practical thermionic converters have used cesium vapor because of the remarkably fortunate combination of three major phenomena. First, Cesium atoms are adsorbed on the emitter and collector surfaces to reduce the work functions of these electrodes to values favorable for energy conversion.

The optimum operating temperature for rubidium–argon–hydrogen over the range 470–650°C was determined to be 535°C. The data indicates that the catalysis reaction is sensitive to the cesium or rubidium vapor pressure with a decrease in rate due to deviation from an optimum.

This unique solution makes it possible to achieve a 10 −6 Torr vacuum level inside the cell in the presence of saturated rubidium vapor, paving the way to building a new class of optical reference cells for atomic spectroscopy. Because the level of vacuum is high enough, experiments with cold atoms are potentially feasible.

Rubidium is no exception to this rule, being silvery-white and melting at 39 ºC. The element has two naturally occurring isotopes. Rubidium-85 is the dominant form, accounting for 72 per cent of the total, while most of the remainder is the radioactive rubidium-87, which has a half-life of 50 billion years.

Vapor cells for NMR gyroscopes typically encapsulate gasses such as cesium or rubidium, which absorb circularly polarized light at specific optical absorption line wavelengths. The absorption of circularly polarized light is used for both the state preparation (pump) and detection (probe) of the alkali gas.

The saturated vapor pressure above a liquid (solid) is described by the Clausius-Clapeyron equation. It is a consequence of the equality between the chemical potentials of the vapor and liquid (solid). The derivation can be found in any undergraduate text on thermodynamics (e.g. Kittel & Kroemer [1]):
