Plasmon electron energy-gain spectroscopy

open access: yesNew Journal of Physics, 2013
We explore multiple energy losses and gains undergone by swift electrons interacting with resonant evanescent light fields. We predict remarkably high gain probabilities in the range of a percentage when the electrons are passing near a resonant ...
