This collective response (wake effect) in-duces a shift of the continuum energy level by more than 100 eV, which is observed by means of Radiative Electron Capture into the K and L-shells of the projectiles. We also observe an increase of the REC probability by 20-50% relative to the probability in a non-perturbed electron gas. The energy shift is in agreement with calculations using the linear response theory, whereas the loca","authors_text":"A. Br\\\"auning-Demian, A. Gumberidze, A. L'hoir, C. Cohen, C. Kozhuharov, C.
