ABSTRACT
We present experimental evidences for consecutive multiple projectile-target-projectile-… (P-T-P-… or T-P-T-…) scattering of the electrons liberated in ion-atom collisions. The highest order of the observed multiple scattering sequences is a quadruple P-T-P-T scattering. We observed the P-T scattering in different collisions, and found strong indications for the accelerating T-P scattering. Distinct signatures of the P-T, P-T-P and P-T-P-T multiple electron scattering contributions to the high-energy part (300 - 3400 eV) of the double differential electron spectra have been separated and identified with the help of reference measurements and auxiliary calculations in single C[sup +] + Xe collisions at 150 and 233 keV/u impact energies. In the collisions of few keV energy ions with inert gas atoms, preliminary results indicate the presence of even higher order scattering contributions.
