Abstract

Abstract : We investigate the dynamical process of optically trapped X 1 Σ + ( v ′′ = 0) state 85 Rb 133 Cs molecules distributed in J ′′ = 1 and J ′′ = 3 rotational states. Abstract : We investigate the dynamical process of optically trapped X 1 Σ + ( v ′′ = 0) state 85 Rb 133 Cs molecules distributed in J ′′ = 1 and J ′′ = 3 rotational states. The considered molecules, formed from short-range photoassociation of mixed cold atoms, are subsequently confined in a crossed optical dipole trap. Based on a phenomenological rate equation, we provide a detailed study of the dynamics of 85 Rb 133 Cs molecules during the loading and holding processes. The inelastic collisions of 85 Rb 133 Cs molecules in the X 1 Σ + ( v ′′ = 0, J ′′ = 1 and J ′′ = 3) states with ultracold 85 Rb (or 133 Cs) atoms are measured to be 1.0 (2) × 10 −10 cm 3 s −1 (1.2 (3) × 10 −10 cm 3 s −1 ). Our work provides a simple and generic procedure for studying the dynamical process of trapped cold molecules in the singlet ground states.
