EXELFS (CHI)-DATA RENORMALIZATION

In this paper, a procedure developed for accurate modeling of the back ground of core edges in electron energy loss spectroscopy (EELS) is de scribed. This procedure is necessary for improving data analysis techn ique 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 possi ble to renormalize the EXELFS chi-data and to ensure the correct use o f the XAFS programs for EXELFS analysis.
