Evidence for Rb‐Rare‐Gas Molecules from the Relaxation of Polarized Rb Atoms in a Rare Gas. Experimental Results

摘要: Relaxation experiments have been performed between 0–200 G on optically polarized Rb atoms in argon, krypton or xenon, at pressures ranging from 0.1 to 20 torr. They clearly show the existence of Rb–Ar, Rb–Kr and Rb–Xe molecules low binding energy (smaller than kT). Molecular parameters such as lifetime, spin‐orbit coupling constant, formation rate, constant mass action, etc., are measured, evaluated when they cannot be directly measured. Experimental values diffusion coefficient gas (except xenon) disorientation cross sections by usual binary collisions also obtained.
