Abstract : Molecular ion beams D+, D+2 and D+3, at 300 and 400 keV-Atom, were used to investigate the correlation in the motions of the molecular fragments inside a 180 µg-cm2 thick Au foil. The probabilities of detecting any number of fragments and the integral angular distributions were determined using a variable round iris aperture in front of the detector, controlled from outside the scattering chamber. A monitor detector was used for normalization. The results show a 50% enhancement of the probability for detecting all the molecular ions fragments at small angles. The data of D+2 ions is reasonably well reproduced by a very simplified form of a wake potential without any free parameters. The data of D+3 show that the wake potential for this case is stronger than the one expected from one leading fragment.
