用核探针测试量子关联
Testing quantum correlations with nuclear probes
摘要：
我们研究了量子关联测量在核物理实验中的可行性。在第一种方法中，我们测量了在1H（d，2He）和12C（d，2He）核电荷交换反应中产生的单自旋（1S0）质子对的自旋相关性。该实验进行了优化，为一个干净的准备2He单重态，并提供了一个2 π检测几何的两个质子在出口通道。我们的研究结果证实了这些研究的设置的有效性，尽管在可行性研究期间记录的小数据样本的限制。
英文摘要：
We investigated the feasibility of quantum-correlation measurements in nuclear physics experiments. In a first approach, we measured spin correlations of singlet-spin (1S0) proton pairs, which were generated in 1H(d,2He) and 12C(d,2He) nuclear charge-exchange reactions. The experiment was optimized for a clean preparation of the 2He singlet state and offered a 2pi detection geometry for both protons in the exit channel. Our results confirm the effectiveness of the setup for theses studies, despite limitations of a small data sample recorded during the feasibility studies.
