Abstract
The explanation of formation of Polycyclic Aromatic Hydrocarbons in space is one of the biggest challenges of modern astrochemistry. Neutral gas phase pathways are complicated and have extremely low cross sections.
Here we present the experimental evidence for the effective formation of benzene cation in small acetylene clusters, after electron irradiation. This can be important heterogeneous chemistry step of PAH formation occurring on interstellar ices.
