Contribution

It introduces a theoretical framework for radiative formation of cold molecular ions and examines threshold behaviors in atom-ion collisions.

Threshold behavior observed in atom-ion collision systems.

Predictions applicable to experimental cold ion-atom systems.

Abstract

We discuss theoretically ion-atom collisions at low energy and predict the possibility of formation of cold molecular ion by photoassociation. We present results on radiative homo- and hetero-nuclear atom-ion cold collisions that reveal threshold behaviour of atom-ion systems.
