摘　　要：We have produced ultracold polar RbCs molecules via photoassociation starting from laser-cooled 85Rb and 133Cs atoms in a dual−species,forced dark magneto-optical trap.The formed electronically excited RbCs∗molecules correlated to the Rb(5S_(1/2))+Cs(6P_(1/2))dissociation limit are observed by trap loss spectroscopy.Following the decay of these excited RbCs*molecules,the formed ground state molecules are directly ionized by a two-photon single-color pulse dye laser,which is a new ionization mechanism for ground state RbCs molecules and thence detected by time-of-flight mass spectroscopy.
