Abstract
The work presents the X-ray absorption fine structure (XAFS) technique for measuring the X-ray absorption coefficient of NiCO3 in the X-ray energy range of 8271.2 to 8849.4 eV using scanning EXAFS beam line (BL-09) at Indus-2 synchrotron radiation source facility, Raja Ramanna Centre for Advanced Technology (RRCAT) at Indore, India. The result represents the absorption coefficient data for NiCO3 in the XAFS region of K-edge of Ni. However, the results are compared to theoretical predictions obtained from X-COM and FFAST methods. There is a maximum deviation which is found exactly near the K-edge jump and decreases as we move away from the absorption edge.
