Measurement of velocity distribution for strontium atom beam by Zeeman Scanning technology
利用塞曼扫频法实现对减速锶原子束速度分布的直接测量

We measure the velocity distribution of the strontium atomic beam directly by Zeeman scanning technology. The most probable velocities of atomic beam before and after Zeeman deceleration are 420 m/s and 60 m/s respectively. Zeeman scanning method is much convenient than other detect ways. Because of its direct fluorescence observation, it has a high accuracy relatively.
