寻找交换反对称双光子态
Search for exchange-antisymmetric two-photon states
摘要：
原子双光子J=0 $\leftrightarrow$ J '= 1跃迁对于相同能量的光子是禁止的。这个选择规则与光子服从玻色-爱因斯坦统计的事实有关。我们通过研究Ba原子中的跃迁来寻找对这一选择定则的微小违反。我们对光子处于交换反对称态的概率$v$设置了一个限制：$v<1.2\cdot10^{-7}$。
英文摘要：
Atomic two-photon J=0 $\leftrightarrow$J'=1 transitions are forbidden for photons of the same energy. This selection rule is related to the fact that photons obey Bose-Einstein statistics. We have searched for small violations of this selection rule by studying transitions in atomic Ba. We set a limit on the probability $v$ that photons are in exchange-antisymmetric states: $v<1.2\cdot10^{-7}$.
