Title: Measuring the van der Waals forces between a Rydberg atom and a metallic surface

Journal Article · · Phys. Rev. A; (United States)

We have observed the deflection of Rydberg atoms towards a metallic surface by the van der Waals force. Cs and Na atoms in states of principal quantum number n were sent between two parallel gold-coated mirrors, spaced by a gap w (2.1 ..mu..mless than or equal towless than or equal to8.5 ..mu..m). We measured the value n/sub m/ at which the transmission cuts off and from the variation of n/sub m/ versus w, we obtained a measure of the atom-surface interaction. For 12<30 this interaction is 3--4 orders of magnitude larger than for ground-state atoms, and it obeys the scaling laws of the Lennard-Jones model.
