An analytical approach to ion energy loss distributions capable of simplifying medium energy ion scattering (MEIS) spectral analysis is presented. This analytical approach preserves the accuracy of recent numerical models that evaluate energy loss effects overlooked by standard calculations based on the Gaussian approximation. Results are compared to first principle calculations and experimental MEIS spectra from 0.2- to 1.5-nm-thick HfO(2) films on Si, supporting the application of this analytical model for proton scattering in the kinetic energy range from 100 to 200 keV.
