The underlying physical processes in the substrate were already explored for several projectile ions. However, studies of ion interaction with precursor molecules for beam-assisted deposition are almost nonexistent. Here, we explore the interaction of various projectile ions with iron pentacarbonyl. We report fragmentation patterns of isolated gas-phase iron pentacarbonyl after interaction with 4 He + at a collision energy of 16 keV, 4 He 2+ at 16 keV, 20 Ne + at 6 keV, 20 Ne 4+ at 40 keV, 40 Ar + at 3 keV, 40 Ar 3+ at 21 keV, 84 Kr 3+ at 12 keV, and 84 Kr 17+ at 255 keV. These projectiles cover interaction regimes ranging from collisions dominated by nuclear stopping through collisions dominated by electronic stopping to soft resonant electron-capture interactions. We report a surprising efficiency of Ne + in the Fe(CO) 5 decomposition. The interaction with multiply charged ions results in a higher content of parent ions and slow metastable fragmentation due to the electron-capture process. The release of CO groups during the decomposition process seems to take off a significant amount of energy. The fragmentation mechanism may be described as Fe being trapped within a CO cluster.
