测量了Pb_（3+）中金和铅的4f_（5/2）和4f_（7/2）峰的结合能，发现与文献值不同。我们建议以下值：对于金，4f 5/2= 87.7 eV，4f 7/2= 84.0 eV;对于Pb 304，Pb 4f 5/2= 142.7 eV，Pb 4f 7/2= 137.8 eV。当在非导体中进行结合能测量时，表面电荷可能会积聚，导致观察到的结合能出现误差。评估了Mo 03、气相沉积金和碳杂质补偿表面电荷误差的能力。得出的结论是，使用金和碳，而不是Mo 03，作为外标，将允许校正表面电荷误差。然而，碳1 s结合能的不确定性使其成为一个不令人满意的标准。讨论了选择合适结合能参考值的标准。
The bindingenergies of the4f5/2 and 4f7/2 peaks of gold and lead in Pb3 (> 4 were measured and found to differ from the previous literature values. We suggest the following values: for gold, 4f5/2= 87.7 eV, 4f7/2= 84.0 eV; for Pb304, Pb 4f5/2= 142.7 eV, Pb 4f7/2= 137.8 eV. When making binding energy measurements in noncon-ductors, a surface charge may build up, causing an error in the observed binding energies. The abilities of Mo03, vapor-deposited gold, and carbonimpurity to compensate for surface charge errors were evaluated. It was conclud-ed that the use of gold and carbon, but not Mo03, as an external standard would allow one to correct for surface charge errors. However, uncertainty about the carbon 1s binding energy makes it an unsatisfactory standard. Cri-teria for appropriate binding energy references are dis-cussed.
