摘要: We observe the dynamic formation of quasibound Cs2 molecules near Feshbach resonances in a cold sample atomic cesium. Using an external probe beam, more than 15 weakly coupled molecular states are detected with high sensitivity, whose collisional cross sections as small sigma=2 x 10(-16) cm(2). By modeling molecule and dissociation processes rate equations, we conclude that at density 10(13) cm(-3) temperature 5 microK, 5(1)x10(5) single rovibrational state coexist 10(8) Cs atoms our trap.
