Abstract：
The escape peaks in synchrotron radiation X-ray fluorescence (SR-XRD) spectra generating from Si(Li) detector can disrupt seriously the qualitative and quantitative analysis.Discrimination to escape peaks in experiments was performed.The escape peak position and intensity of 12 elements from K K _αto As K _α,for each of the 14 specimens,are measured.The differences of standard and experimental values of escape peak and the nearest major peak are compared.The errors are less than 10% in general.The ratios of intensity of escape peak and major peak are calculated using a simplified emitting distribution model of Si K _αexcited by X-ray.The ratios,both calculated and experimental,descend approximately from 1% to 0.1% with the atom ordinal number increasing.
