    "abstract": "We consider the bipartite spin entanglement between two identical fermions\ngenerated in spin-independent scattering. We show how the spatial degrees of\nfreedom act as ancillas for the creation of entanglement to a degree that\ndepends on the scattering angle, $\\theta$. The number of Slater determinants\ngenerated in the process is greater than 1, corresponding to genuine quantum\ncorrelations between the identical fermions. The maximal entanglement\nattainable of 1 ebit is reached at $\\theta=\\pi/2$. We also analyze a simple\n$\\theta$ dependent Bell\u0027s inequality, which is violated for\n$\\pi/4\u003c\\theta\\leq\\pi/2$. This phenomenon is unrelated to the symmetrization\npostulate but does not appear for unequal particles.",
