We consider the accuracy of holographic inversions of electron emission data at ∼103 eV to yield atomic positions. Theoretical calculations for small clusters of 2-5 atoms in both single and multiple scattering show that self-interference effects may be present, and that forward-peaked scattering tends both to shift peaks by as much as 0.5-1.0 Å from the true positions and to elongate images along forward-scattering directions. However, eliminating forward-peaked intensities before inversion significantly improves image quality.
