  We suggest that low energy electrons, released by resonant decay processes,
experience substantial scattering on the electron density of excited electrons,
which remain a spectator during the decay. As a result, the angular emission
distribution is altered significantly. This effect is expected to be a common
feature of low energy secondary electron emission. In this letter, we exemplify
our idea by examining the spectator resonant interatomic Coulombic decay
(sRICD) of Ne dimers. Our theoretical predictions are confirmed by a
corresponding coincidence experiment.
