THE NUMERICAL CALCULATION USED IN THICK TARGET PIXE ANALYSES

Abstract: The numerical calculation were used to correct the measured K X-ray intensities in thick target PIXE analyses for the following matrix effects: slowing down of protons,absorption of characteristic X-ray,and X-ray induced X-ray emission in the sample.The efficiency calibrations for PIXE analysis system were made by means of the Monte Carlo technique.Based on these corrections and calibrations,the PIXE analysis results on some thick speciments made by ourself were obtained without the use of standard and they showed a good agreement between the measured and the known values of contents.
