Fingerprints of entangled states in reactions with rare isotopes

We study the presence of entangled states of nucleon pairs from nuclear decays and in reactions with exotic nuclei, e.g., ¹¹Li, or ⁶He. It is shown that the fingerprints of entangled states in these subsystems are visible in correlation measurements and can be accessed with present experimental techniques. This shows that not only atomic and optical systems, but also nuclear systems serve as important tools to obtain dichotomic outcomes for tests of the Einstein–Podolsky–Rosen paradox.
