## Description

- description: We have determined electron inelastic mean free paths (IMFPs) and surface-electronic
    excitation parameters (SEPs) of Au and Cu in the 200 – 5000 eV from their elastic
    peak intensity ratios without reference IMFP values. This proposed method does
    not require the IMFP values of the reference material. The measurements of elastic
    peak intensities of these elements were done with noble CMA system. The elastic
    peak intensities were also calculated from two parameter sets (IMFPs and SEPs
    for both elements) with Monte Carlo method. By comparison of these two EPI ratios
    as changing the parameter sets, we have estimated their IMFPs and SEPs in the
    200 – 5000 eV energy range. The resulting IMFPs of Au and Cu were in good agreement
    with optical IMFPs over 1000 eV energy range.
