摘要：

We report the magneto-optical trapping of ytterbium atoms using the 6s(21)S(0)-6s6p(3)P(1) intercombination transition. The magneto-optical trap is continuously loaded from an atomic beam decelerated by a Zeeman-tuned atomic-beam slower operated at the 6s(21)S(0)-6s6p(1)P(1) transition. Among seven stable isotopes of ytterbium, six isotopes;of Yb-170, Yb-171, Yb-172, Yb-173, Yb-174, and Yb-176 are successfully trapped. The number and density of the trapped atoms are about 10(8) and 10(11) cm(-3), respectively. The temperature of atoms is estimated to be about 20 mu K from the time-of-flight measurement. The decay time of the trapped atoms after stopping the loading of atoms is bout 3 s. [S1050-2947(99)50208-4].
