Abstract

Measurements of the velocity distributions of heavy Rydberg ion-pair states formed through electron transfer in collisions between Rydberg atoms and attaching targets are used to probe the dynamics of dissociative electron attachment.

Use of heavy-Rydberg ion-pair states to probe dissociative electron attachment

M Kelley, Sitti Buathong, F. B. Dunning

Electron transfer in collisions between Rydberg atoms and targets that attach free low-energy electrons can lead to the formation of heavy-Rydberg ion-pair states comprising a positive-negative ion pair that orbit each other at large separations weakly bound by their mutual electrostatic attraction. It is shown that measurements of the velocity distribution of the ion-pair states produced in such collisions provide a novel probe of the dynamics of dissociative electron attachment.

Production of heavy-Rydberg ion-pair states in Rydberg atom collisions

M. Cannon, C Wang, F. B. Dunning

The formation of bound heavy-Rydberg ion-pair states through electron transfer in collisions between K( n p) Rydberg atoms and attaching targets is being examined, Measurements show that low- n collisions with a wide variety of targets can lead to formation of bound ion-pair states. Under appropriate conditions a small fraction of these can subsequently dissociate as free ions through internal-to-translational energy transfer, with typical lifetimes of ∼ 1-5 μs.
