Egerton, R.; Blackburn, A.; Herring, R.; Wu, L. & Zhu, Y. Direct measurement of the PSF for Coulomb delocalization--a reconsideration. Ultramicroscopy, 2021, 230, 113374
An interpretation of Coulomb delocalization, which limits the spatial resolution of inelastic TEM or STEM images, is given. We conclude that the corresponding point spread function cannot be measured as a broadening of a STEM probe.
