A schematic of experimental setup consisting of a liquid jet target source, a liquid cold trap, and a TOF mass spectrometry system. The flight tube entrance has an aperture of 1.0 mm in diameter.
Variation in liquid ethanol temperature as a function of the distance from a nozzle exit estimated from Ref. 8. The freezing point is 158.65 K at 1 atm.
TOF mass spectrum of positive secondary ions emitted from a liquid ethanol target bombarded by 2.0 MeV ions.
TOF mass spectrum of negative secondary ions emitted from a liquid ethanol target bombarded by 2.0 MeV ions.
Intensities of various secondary ions as a function of the deviation of the incident ion beam from the liquid beam axis. Data are normalized to the intensity of .
Lower mass spectrum of positive secondary ions expanded from Fig. 3.
Cluster size distributions of and as a function of the cluster size n. Also shown are other experimental results obtained for liquid ethanol by UV laser irradiation (Ref. 10) and solid ethanol by keV ion impacts (Refs. 25 and 26).
Temperature dependence of negative cluster ions of plotted as a function of the cluster size n.
