Near node photoelectron holography

A new experimental geometry for photoelectron holography is proposed. It exploits the anisotropic nature of photoelectron waves. Forward scattering is suppressed in a geometry where the scattered electrons are measured close to a node of the electron source wave. As a consequence the quality of holographic reconstructions improves considerably. The fairly complex structure of the Cs-1CO-Ru(0001)-(2 × 2) phase is treated as a model case.
