Diffuse elastic scattering of electrons by single nm-sized defects in ion-irradiated Au was measured quantitatively. Diffuse scattering from isolated single dislocation loops was separated from Bragg scattering at a weakly excited diffraction peak. Results were compared with calculations for diffuse scattering of X-rays and electrons. The pattern in the diffuse scattering within a single reciprocal lattice plane often revealed the loop geometry, size, and interstitial or vacancy nature. Defect images using only diffuse scattering were achieved with high sensitivity and good resolution by a hollow-cone dark-field method.
