Physical Review A, 1986
Ion formation in sodium vapor (\ensuremath{\sim}${10}^{11}$ ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}3}$) containing Rydberg atoms (18\ensuremath{\le}n\ensuremath{\le}35) was investigated. Both atomic ions and diatomic molecular ions resulting from collisions between highly excited sodium, ${\mathrm{Na}}^{\mathrm{*}\mathrm{*}}$, and Na(3s) were observed.

Resonant Rydberg-Atom-Rydberg-Atom Collisions
Physical Review Letters, 1981We have observed the sharply resonant enhancement of the cross section of the collision process $ns+ns\ensuremath{\rightarrow}np+(n\ensuremath{-}1)p$ between two $\mathrm{Na}ns$ ($16l~nl~27$) atoms which occurs when the levels are shifted by an electric field so that the $ns$ level lies midway between the two $p$ states.

Squeezing in a Rydberg Atom Maser
Physical Review Letters, 1985We show theoretically that a Rydberg atom maser produces during its evolution a squeezed field with sub-Poissonian statistics. We give a semiclassical interpretation of this effect.

Subrecoil cooling of Rydberg atoms
Physical Review A, 1995Two mechanisms for production of an ensemble of atoms in a highly excited state with very narrow distribution of the atomic center-of-mass momentum (cold Rydberg atoms) are proposed. The mechanisms are based on velocity-selective $\ensuremath{\pi}$ pulses and coherent population trapping in three-level cascade systems with the uppermost state being the
