Dissociation and Decay of Ultra-cold Sodium Molecules
arXiv:cond-mat/0311558 · doi:10.1103/PhysRevLett.92.180402
Abstract
The dissociation of ultracold molecules is studied by ramping an external magnetic field through a Feshbach resonance. The observed dissociation energy shows non-linear dependence on the ramp speed and directly yields the strength of the atom-molecule coupling. In addition, inelastic molecule-molecule and molecule-atom collisions are characterized.
