    "abstract": "The influence of the geometric phase, in particular the Berry phase, on an\nentangled spin-1/2 system is studied. We discuss in detail the case, where the\ngeometric phase is generated only by one part of the Hilbert space. We are able\nto cancel the effects of the dynamical phase by using the ``spin-echo\u0027\u0027 method.\nWe analyze how the Berry phase affects the Bell angles and the maximal\nviolation of a Bell inequality. Furthermore we suggest an experimental\nrealization of our setup within neutron interferometry.",
