论文摘要
GD的L子壳Coster Kronig（CK）过渡因子已通过两种不同的实验方法在实验中确定，并将其与可用文献数据进行了比较。一方面，应用了无参考X射线荧光（XRF）分析，并使用能量分散性检测器进行了分析。除了确定L子壳荧光产率外，还允许使用此方法，因为可以确定绝对入射和发射的X射线光子通量。另一方面，基于修饰的von Hamos几何形状的波长色散光谱仪使用全缸高度退火的热石石墨晶体，以实验在独立实验中对CK过渡因子的实验验证。由于能够更好地区分不同X射线发射线以验证无参考XRF结果的能力，因此允许使用这种高能量分辨率光谱仪。对于这两个实验，使用校准仪器都使该规定对获得的结果有了可靠的不确定性预算。
The L subshell Coster Kronig (CK) transition factors of Gd have been experimentally determined by means of two different experimental approaches and compared to available literature data. On the one hand reference-free X-ray fluorescence (XRF) analysis using an energy-dispersive detector was applied. This method permitted in addition to determine the L subshell fluorescence yields since the absolute incident and emitted X-ray photon flux can be determined. On the other hand a wavelength dispersive spectrometer based on a modified von Hamos geometry using a full cylinder highly annealed pyrolithic graphite crystal for an experimental validation of the CK transition factors in an independent experiment. The use of this high energy resolution spectrometer allowed thanks to the capability to better discriminate the different X-ray emission lines to validate the reference-free XRF results. For both experiments the use of calibrated instrumentation enabled the provision a reliable uncertainty budget on the results obtained.
