Ionization-Driven Dehydrogenation and Molecular Growth in Gas-Phase Adamantane Clusters
Sumit Srivastav, Per Eng-Johnsson, Raimund Feifel +4
We investigate fragmentation and molecular growth induced by keV ions in initially neutral gas-phase adamantane clusters, the simplest diamondoid molecule (Ad, CH). U…

Isomer effects on neutral-loss dissociation channels of nitrogen-substituted PAH dications
Sumit Srivastav, Sylvain Maclot, Alicja Domaracka +2
We investigate two nitrogen-containing isomers of polycyclic aromatic hydrocarbons (PAHs), quinoline (Q) and isoquinoline (IQ), of composition CHN in collisions with 7~keV…

Fast ion diffraction of protons on NaCl, the discovery of GIFAD
Patrick Rousseau, Philippe Roncin
Grazing incidence fast atom diffraction (GIFAD or FAD) has become a technique to track the surface topology of crystal surface at the atomic scale. The paper retraces the events th…
