Energetic ions lose some of their kinetic energy when interacting with electrons or nuclei in
matter. Here, we discuss combined experimental and theoretical studies on such impulse …

Laboratory studies play a crucial role in understanding the chemical nature of the interstellar
medium (ISM), but the disconnect between experimental timescales and the timescales of …

We present dynamical studies of the dissociation of polycyclic aromatic hydrocarbon (PAH)
radical cations in their ground electronic states with significant internal energy. Molecular …

We present a review of the capabilities of the density functional based Tight Binding (DFTB)
scheme to address the electronic relaxation and dynamical evolution of molecules and …

The reaction mechanisms for the loss of C2H2 from the ions of anthracene, phenanthrene,
tetracene, and pyrene were calculated at the B3-LYP/6-311++ G (2d, p) level of theory and …

We have investigated the effectiveness of molecular hydrogen (H 2) formation from
Polycyclic Aromatic Hydrocarbons (PAHs) which are internally heated by collisions with keV …

The interactions of electrons with molecular systems under various conditions are essential
to interdisciplinary research fields extending over the fundamental and applied sciences. In …

We have investigated the photo-stability of pristine and super-hydrogenated pyrene cations
(${{\rm {C}}} _ {16}{{\rm {H}}} _ {10+ m}^{+}, m= 0, 6,{\rm {}}\,{\rm {or}}\,{\rm {}} 16$) by means …

We present scaling laws for absolute cross sections for non-statistical fragmentation in
collisions between Polycyclic Aromatic Hydrocarbons (PAH/PAH+) and hydrogen or helium …

The whole process following collisions of polycyclic aromatic hydrocarbons (PAHs) with high
energetic protons is modeled and compared to the experimental mass spectrum, allowing to …
