用全光Ramsey共振技术测量Cs的禁戒张量极化率
Measurement of the forbidden tensor polarizability of Cs using an all-optical Ramsey resonance technique
摘要：
我们在热原子束中利用光抽运探测技术测量了Cs原子基态强抑制的电张量极化率。结果与以前的测量结果一致，并证实了长期存在的理论值的差异。预计未来的总不确定性降低到1%的水平，使这个数量的原子结构计算涉及短程内原子相互作用的一个有价值的测试。
英文摘要：
We have measured the strongly suppressed electric tensor polarizability of the Cs ground state using an optical pump-probe technique in a thermal atomic beam. The result agrees with a previous measurement and confirms the long-standing discrepancy with a theoretical value. The anticipated future reduction of the total uncertainty to the 1% level makes this quantity a valuable test for atomic structure calculations involving short-range inner-atomic interactions.
