1. INTRODUCTION Beams of atoms and molecules are stalwart tools for spectroscopy and
studies of collisional processes. 1− 4 The supersonic expansion technique can create cold …

Magnetically tunable Feshbach resonances were employed to associate cold diatomic
molecules in a series of experiments involving both atomic Bose and two-spin-component …

Photoassociation is the process in which two colliding atoms absorb a photon to form an
excited molecule. The development of laser-cooling techniques for producing gases at …

Collisions of molecules in a thermal gas are difficult to control. Thermal motion randomizes
molecular encounters and diminishes the effects of external radiation or static …

The goal of the present article is to review the major developments that have led to the
current understanding of molecule–field interactions and experimental methods for …
