TL;DR: In this article, the authors compared the performance of multiphoton resonance ionization (MPRI) of sputtered neutrals with low-dose secondary ion mass spectrometry via the chemisorption of oxygen on polycrystalline indium.

TL;DR: In this article, a serie of couches monomoleculaires de composes organiques (benzene and pyridine) adsorbes sur la facette 111 d'argent en vue d'eclaircir le mecanisme fondamental de dejection des agregats moleculaires.

TL;DR: The mechanism of energy dissipation in argon crystals bombarded by 100 and 5OO eV Ar+ has been examined using classical dynamics in this paper, which indicates that very high yields may be expected and that large molecular Ar clusters may form via recombination in the near surface region.

TL;DR: In this article, a simplified scheme is presented to distinguish between surface and gas-phase fragmentation of molecular ions in SIMS or FABMS experiments, based on the measurement of the polar angle distribution of ejected parent and daughter clusterions and derived from straightforward considerations of classical mechanics.
