EXELFS χ-data renormalization

In this paper, a procedure developed for accurate modeling of the background of core edges in electron energy loss spectroscopy (EELS) is described. This procedure is necessary for improving data analysis technique used in extended energy loss fine structure (EXELFS) spectroscopy via the adaptation of X-ray absorption fine structure (XAFS) analysis programs. With the improved background modeling, it now becomes possible to renormalize the EXELFS χ-data and to ensure the correct use of the XAFS programs for EXELFS analysis.
