Stopping cross-sections of liquid ethanol for swift He ions

Stopping cross-sections of liquid ethanol for swift He ions

Energy loss spectra of 4.0 MeV helium ions after penetrating through liquid phase ethanol have been measured at scattering angles from 10 to 50 mrad. Experimental data were fitted with Monte Carlo simulations using a GEANT4 toolkit, and stopping cross-sections were deduced in an energy range from 1....

Zusammenfassung:Energy loss spectra of 4.0 MeV helium ions after penetrating through liquid phase ethanol have been measured at scattering angles from 10 to 50 mrad. Experimental data were fitted with Monte Carlo simulations using a GEANT4 toolkit, and stopping cross-sections were deduced in an energy range from 1.9 to 4 MeV. Present results are in fairly good agreement with previous experimental data and SRIM2008 values. By applying the Bragg’s additivity rule, the mean excitation energy was deduced as I = 62.0 ± 1.8 eV for liquid ethanol. The present I-value is compared with other experimental and calculated results.
