Inelastic collisions of ultra-cold heteronuclear molecules in an optical trap
Abstract
Ultra-cold RbCs molecules in high-lying vibrational levels of the a3+ ground electronic state are confined in an optical trap. Inelastic collision rates of these molecules with both Rb and Cs atoms are determined for individual vibrational levels, across an order of magnitude of binding energies. A simple model for the collision process is shown to accurately reproduce the observed scattering rates.
