摘要：

A method is introduced joining together forward-scattering diffraction data taken in a small angular window at different photoelectron energies. This method extends the usable range in phase space for three-dimensional image reconstruction. Examples based on theoretical simulations demonstrate that a spatial resolution of less-than-or-equal-to 1 angstrom is achievable. We also show that using a small angular window in the back-scattering geometry eliminates splittings in the reconstructed image.
