摘要： Single caesium atoms in a large-magnetic-gradient vapour-cell magneto-optical trap have been identified. The trapping of individual atoms is marked by the steps in fluorescence signal corresponding to the capture or loss of single atoms. The typical magnetic gradient is about 29\,mT/cm, which evidently reduces the capture rate of magneto-optical trap.

The typical magnetic gradient is about 29 mT/cm, which evidently reduces the capture rate of magneto-optical trap.
