Doubly differential 8-electron emission cross sections A2~(E,,6,)/AE,AflZ, have been measured as a function of the electron energy E, and the electron emission angle 6, for the collision systems 1.4 MeV U-' U33+ on neon and argon. The angular distributions of the emission cross sections show a maximum at 6, = 60", in agreement with parameter-free n-body classical-trajectory Monte Carlo ( ~-C T M C ) calculations. The cross sections show an extreme anisotropy between forward and backward emission compared with those of light-ion data. The cross sections decrease exponentially for 6,2 90". The n -c T M c calculations indicate that the large projectile Coulomb force highly polarises the target-atom electrons in the two-centre field. A large fraction of the ionised electrons are emitted into an angular region of 6, = 60" opposite to the recoiling target ion. The two-centre potential is crucial for the description of such clustered emission of S electrons.
