  We consider the bipartite spin entanglement between two identical fermions
generated in spin-independent scattering. We show how the spatial degrees of
freedom act as ancillas for the creation of entanglement to a degree that
depends on the scattering angle, $\theta$. The number of Slater determinants
generated in the process is greater than 1, corresponding to genuine quantum
correlations between the identical fermions. The maximal entanglement
attainable of 1 ebit is reached at $\theta=\pi/2$. We also analyze a simple
$\theta$ dependent Bell's inequality, which is violated for
$\pi/4<\theta\leq\pi/2$. This phenomenon is unrelated to the symmetrization
postulate but does not appear for unequal particles.
