Resumen:
Fully differential cross sections for single ionization of helium induced by
impact of 100 MeV/u C6+ ions are examined within a quantum-mechanical
distorted wave model. The experimental uncertainties are included in the
theoretical calculations, leading to a quantitative description of the experimental
cross sections. In particular, the ionization cross section for the electron emitted
in the plane perpendicular to the scattering plane is reproduced for the first time
by a full quantum-mechanical model. The role of the internuclear interaction
in this perturbative-regime collision is discussed and found to be unimportant
for the present kinematical conditions./u C6+ ions are examined within a quantum-mechanical
