Resonance ionization spectroscopy measurement of vapor pressure of rubidium iodide

· Appl. Phys. Lett.; (United States)
Resonance ionization spectroscopy has been used to measure vapor pressure data for a solid (RbI) to very low pressures. A pulsed UV laser was used to dissociate RbI molecules in the vapor phase established over a sample at known temperature. The rubidium atoms were then ionized by a two-step process using a dye laser tuned to either of two allowed transitions in the ground-state atomic Rb system. These measurements have extended the RbI vapor pressure versus temperature curve approximatelly 10 orders of magnitude below previously reported experimental data. Although this experiment is limited to RbI, the technique is applicable to a wide variety of solids, both atomic and molecular.
