We have investigated the response of superhydrogenated gas-phase coronene cations upon soft x-ray absorption. Carbon (1s) transitions were resonantly excited at hν=285eV. The resulting core hole is then filled in an Auger decay process, with the excess energy being released in ...

Hydrogenation of pah cations

A First Step Toward H2 formation

Molecular hydrogen is the most abundant molecule in the universe. A large fraction of H2 forms by association of hydrogen atoms adsorbed on polycyclic aromatic hydrocarbons (PAHs), where formation rates depend crucially on the H sticking probability. We have experim ...
