摘要：

We investigate the dynamical process of optically trapped X-1 Sigma(+) (V '' = 0) state (RbCs)-Rb-85-Cs-133 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 (RbCs)-Rb-85-Cs-133 molecules during the loading and holding processes. The inelastic collisions of (RbCs)-Rb-85-Cs-133 molecules in the X1S+ (v '' = 0, J '' = 1 and J '' = 3) states with ultracold Rb-85 (or Cs-133) atoms are measured to be 1.0 (2) x 10(-10) cm(3) s(-1) (1.2 (3) x 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.
