Testing quantum correlations with nuclear probes

Abstract

We investigated the feasibility of quantum-correlation measurements in nuclear physics experiments. In the first approach, we measured spin correlations of singlet-spin (S-1(0)) proton pairs, which were generated in H-1(d,He-2) and C-12(d, He-2) nuclear charge-exchange reactions. The experiment was optimized for a clean preparation of the He-2 singlet state and offered a 2pi detection geometry for both protons in the exit channel. Our results confirm the effectiveness of the setup for these studies, despite limitations of a small data sample recorded during the feasibility studies.
