  Entanglement and symmetrization lead to non-separable states that can modify
physical properties. Using the example of atomic absorption we compare both
types of effects when they are relevant at once. The presence of multi-particle
superpositions largely alters the absorption rates of identical atoms, even
inhibiting the dependence on overlapping for fermions. We also identify a set
of non-standard excluded states related to multi-fermion superposition that
naturally emerge in this context. We propose an arrangement based on the
dissociation of molecules to test these ideas.
