Abstract
A focused 15 keV argon ion beam was used to bombard iced targets, CO 2 and H 2O (at temperature (27 K). The sputtered particles were analyzed by a quadrupole mass spectrometer (QMS). The purpose of the experiment was to measure the percentage of the sputtered particles that originated from the impact sites on the iced targets. Some of the particles that were not induced from ion–iced-CO 2 interaction include, for instance, CO, O and C; these were produced during the disintegration by the QMS of pure CO 2, which is copiously sputtered in ion–iced-CO 2 interaction. The analyzed data will be useful for understanding the chemical reaction in ion–molecule interactions.
