Double differential cross sections d σ/dΩdE were measured for high energetic electrons emitted in heavy ion collisions. Electrons were detected in the energy range of 60 keV-500 keV for various target projectile combinations 66≦ Z= Z+ Z≦145 and projectile velocities between 7 % and 10 % of the speed of light. Clear evidence was found that these electrons stem from the united atom formed during the collision. Slope and height of the spectra are discussed with respect to the momentum distribution of strongly bound states (i.e. the L-shell) at momenta far above the mean value. In addition for the systems S, Ni, Br→Pb electrons were detected in coincidence with K x-rays of Pb. By this method the contribution of the K-shell of the combined system to the total spectrum could be separated. Binding energies of the K-shell were estimated by a slope comparison between the coincident and single spectrum. The resulting values are close to the united atom limit. [ABSTRACT FROM AUTHOR] |
