Abstract

Photoassociative ionization (PAI) was the first inelastic process studied in cold samples of trapped atoms.1 Two slowly moving ground-state atoms collide and, during the collision, absorb one photon to a singly excited molecular state that accelerates the atoms toward each other. During this motion, the absorption of a second photon to a doubly excited molecular state subsequently leads to autoionization of the molecule. The rate of AI, kAI, is determined by the equation.
