Gold



The Au 4f7/2 ISO standard binding energy for metallic gold used for calibration is 83.96 eV (for monochromatic Al K(alpha) X-rays).
Typical fitting parameters for pure sputter cleaned gold (10 eV pass energy) include:
FWHM ~ 0.59 eV, GL(86) peak-shape
Au 4f7/2 - Au 4f5/2 splitting ~ 3.67 eV
