PIXE (Proton induced x-ray emission) by proton beam is important technique to find out qualitative and qualitative analysis of element present in the specimen. Quantity of the element directly related to x-ray production cross section. Many literature shows discrepancy between theoretical and experimental x-ray cross section. In this work, x-ray production cross section calculated by ECPSSR theory with 25% variation of screening constant for L sub-shell and compared with experimental measured
