The interaction of slow ions ( v ∼ 0.4 a.u. ) with a small polycyclic aromatic hydrocarbon, namely anthracene (C 14 H 10 ), is studied in the gas-phase either with the isolated molecule or with a pure cluster target. We discuss the ionization and f

Electron-induced dissociations of gas-phase ternary copper-2,2′-bipyridine complexes of Gly-Gly-Gly and Gly-Gly-Leu were studied on a time scale ranging from 130 ns to several milliseconds using a combination of charge-reversal (+CR−) and electro

Ion nanocalorimetry is used to measure the effects of electron kinetic energy in electron capture dissociation (ECD). With ion nanocalorimetry, the internal energy deposited into a hydrated cluster upon activation can be determined from the number of

The residual activity induced in particle accelerators is a serious issue from the point of view of radiation safety as the long-lived radionuclides produced by fast or moderated neutrons and impact protons cause problems of radiation exposure for st
