In this work, a theoretical analysis of the impact of the multiple ionization of uracil by 3.5 MeV/u C6+ is developed in the framework of a classical trajectory Monte Carlo method, as recently introduced for multi-electronic targets. The electron emission contribution arising from the multiple electron ionization is explicitly determined and the emission geometries and the reaction regions for double and triple ionization are explicitly identified. The present results suggest that double ionization is mainly characterized by the emission of slow electrons with a relative angle of 80∘–120∘. For triple ionization, on the other hand, the emission seems to occur with the three electrons holding similar interelectronic angles.
