过去,一般视X-光激发的俄歇峰(XAS或XAES)为X-光电子谱(XPS)中的寄生产物。近年来,由于“俄歇参数”概念的提出,以及不断地注意到高分辨N(E)俄歇谱像XPS一样含有丰富的化学信息,XAS已有发展成为一个独立的电子能谱学分支的倾向。但是,由于一般XPS仪器的Mg/Al双阳极X-光激发源只能产生周期表上大约一半元素的强俄歇峰,这在很大程度上限制了XAS In the past, Auger peaks (XAS or XAES), which are typically X-ray excited, are parasitic products in X-ray photoelectron spectroscopy (XPS). In recent years, XAS has evolved into an independent branch of electron spectroscopy due to the concept of “Auger parameters” and the constant awareness that high-resolution N (E) Auger spectroscopy is as abundant as XPS tendency. However, since the Mg / Al dual anode x-ray excitation source of a typical XPS instrument can only produce a strong Auger peak of about one-half of the elements of the periodic table, this largely limits the XAS
