    "abstract": "We investigated the feasibility of quantum-correlation measurements in\nnuclear physics experiments. In a first approach, we measured spin correlations\nof singlet-spin (1S0) proton pairs, which were generated in 1H(d,2He) and\n12C(d,2He) nuclear charge-exchange reactions. The experiment was optimized for\na clean preparation of the 2He singlet state and offered a 2pi detection\ngeometry for both protons in the exit channel. Our results confirm the\neffectiveness of the setup for theses studies, despite limitations of a small\ndata sample recorded during the feasibility studies.",
