摘要: X光电子谱(XPS)已在固体表面成分分析及表面电子能态的研究中获得了广泛的应用。但是由于常用的X光源的非单色性以及电子能谱仪本身的仪器传递特性,常使X光电子谱的谱形加宽,分辨率降低。为此,常采用退卷积的方法对XPS实验数据进行数字处理[1],以提高其分辨率。在退卷积时,首先必须知道谱线的加宽函数。我们采用了两种方法对加宽函数进行了测量,并获得一致的结果。

Abstract: The transmission function of the electronic energy spectroscope can be obtained from XPS core level speotra by the deconvolution method. Making convolution of the frequency distribution function of X-ray source with it, we have calculated the XPS line shape widening function. The result agrees well with that obtained from the valence level speotra of transition metals.
