Experimental benchmark data for Monte Carlo simulated radiation effects of gold nanoparticles. Part II: Comparison of measured and simulated electron spectra from gold nanofoils

Electron emission spectra of a thin gold foil after photon interaction were measured over the energy range between 50 eV and 9500 to provide reference data for Monte Carlo radiation-transport simulations. Experiments performed with HAXPES spectrometer at PETRA III high-brilliance beamline P22 DESY (Hamburg, Germany) energies just below above each L-edges, i.e., 11.9 keV, 12.0 13.7 13.8 14.3 14.4 keV. The analyzed obtain absolute values particle radiance emitted electrons per incident flux. Simulations experiment using codes Penelope Geant4. Comparison simulated results shows good qualitative agreement. When simulation are convolved curves that take into account effect lifetime broadening, line shapes photoelectron Auger peaks similar those observed experimentally obtained. On an scale, experiments tend give higher electron lower studied as well Au L3 photoelectron. This is attributed linear polarization beam in which not considered codes.
