摘要：
测量了金纳米粒子（AuNPs）在光子相互作用后、能量范围为50 eV至9500 eV的电子发射谱，旨在为蒙特卡罗辐射输运模拟提供参考数据。实验在德国汉堡DESY的PETRA III高亮度P22光束线上使用HAXPES谱仪进行，光子能量分别位于每个金L吸收边之下和之上，即11.9 keV、12.0 keV、13.7 keV、13.8 keV、14.3 keV和14.4 keV。研究重点是一个平均直径为11.0 nm的金纳米粒子样品，该样品置于薄碳箔上。此外，还对5.3 nm金纳米粒子样品以及金箔和碳箔参考样品进行了补充测量。同时开展了用于校准光子通量监测器、表征电子谱仪透射函数以及确定光子束尺寸的进一步测量。这使得能够确定每个入射光子通量下二次电子光谱粒子辐射度的绝对值。本文介绍了实验和原始数据分析流程，回顾了纳米粒子样品所获得的数据，并讨论了这些数据的局限性。
英文摘要：
Electron emission spectra of gold nanoparticles (AuNPs) after photon interaction were measured over the energy range between 50 eV and 9500 eV to provide reference data for Monte Carlo radiation-transport simulations. Experiments were performed with the HAXPES spectrometer at the PETRA III high-brilliance beamline P22 at DESY (Hamburg, Germany) for photon energies below and above each of the gold L-edges, i.e., at 11.9 keV, 12.0 keV, 13.7 keV, 13.8 keV, 14.3 keV, and 14.4 keV. The study focused on a sample with gold nanoparticles with an average diameter of 11.0 nm on a thin carbon foil. Additional measurements were performed on a sample with 5.3 nm gold nanoparticles and on reference samples of gold and carbon foils. Further measurements were made to calibrate the photon flux monitor, to characterize the transmission function of the electron spectrometer and to determine the size of the photon beam. This allowed the determination of the absolute values of the spectral particle radiance of secondary electrons per incident photon flux. The paper presents the experimental and raw data analysis procedures, reviews the data obtained for the nanoparticle samples and discusses their limitations.
