我们报告了一个旨在确定6 He的纯Gamow-Teller衰变中电子和反中微子之间的角相关系数的实验状态。这种测量的动机是寻找张量类型的贡献存在的弱相互作用。该实验使用了一种装置，其中6 He离子被限制在一个新型的透明Paul阱中。同时探测到电子和反冲离子，推导出角相关系数。首次记录了直接在陷阱中的衰变。
We report on the status of an experiment aiming to determine the angular correlation coefficient between the electron and the anti‐neutrino in the pure Gamow‐Teller decay of 6He. Such measurement is motivated by the search for the presence of tensor type contributions to the weak interaction. The experiment uses a setup where 6He ions are confined in a novel transparent Paul trap. Electrons and recoiling ions are detected in coincidence to deduce the angular correlation coefficient. First direct in trap decays have been recorded.
