A correlation of secondary electrons emitted in the forward and in the backward directions has been studied for 1.8 MeV/u Ar ions bombarding carbon foils. Appreciable correlation has been observed not only for thin targets but also for thick targets where no correlation was expected. It is shown that a classical trajectory Monte Carlo simulation including conversion of bulk plasmons into electron-hole pairs which extends over the target can reproduce the observation qualitatively.
