构造了一种放电型原子束炉，并对其在ybi亚稳态的填充性能进行了研究。本文首次用激光诱导荧光法测定了Yb I的基态4f146s21S0和亚稳态4f135d6s2(7/ 2,3 /2)5的相对居群。结果表明，随着放电电流的增大，亚稳态占比增大，基态占比减小到30%。该方法也适用于其他元素。
An atomic beam oven of a discharge type is constructed and the performance in populating a metastable state of Yb I is examined. The relative populations of the ground state 4f146s21S0 and the metastable state 4f135d6s2 (7/2, 3/2)5 of Yb I are measured for the first time by the laser-induced fluorescence method. It is found that the population of the metastable state increases with the discharge current and that of the ground state decreases to 30%. The method is also applicable for other elements.
