Abstract: | The image force for fast (80 kV) electrons has been observed using the small electron microprobe available in a scanning transmission electron microscope, and imaging the surface plasmon losses. Preliminary results for the field at grazing incidence to an MgO surface qualitatively agree with the classical theory. The long range decay is found to be exponential. |
