    "abstract": "In this note we discuss the effect of the unpolarized state in the\nspin-correlation measurement of the $^1S_0$ two-proton state produced in\n12C(d,2He) reaction at the KVI, Groningen. We show that in the presence of the\nunpolarized state the maximal violation of the CHSH-Bell inequality is lower\nthan the classical limit if the purity of the state is less than $ \\sim\n\\verb+70%+$. In particular, for the KVI experiment the violation of the\nCHSH-Bell inequality should be corrected by a factor $\\sim\\verb+10%+$ from the\npure $^1S_0$ state.",
