Measurement of real and imaginary form factors of silver atom using a high resolution HPGe detector

Abstract

The real and imaginary form factors of silver atom have been determined by using EDXRF method. The K x-ray photons in the energy range from 8.62 keV to 52.18 keV are generated by sending 59.56 keV gamma photons from 241 Am radioactive source on various targets. These K x-ray photons are transmitted through silver foils of suitable thickness. The incident and transmitted K x-ray photon intensities have been measured with a high resolution HPGe detector which is coupled to 16K MCA. The photoelectric cross sections at different K x-ray energies have been determined by measuring the intensities of the incident and transmitted x-ray photons. From these photoelectric cross section values, the imaginary form factors and the real form factors have been determined at various photon energies. Measured imaginary and real form factor values have been compared with theoretical values predicted by XCOM [23] and FFAST [24].

Calculation of The Imaginary Part of Atomic Form Factor For X-ray In Nickel

“…This includes reflection, refraction and absorption of x-rays. The spatial distribution of atomic electrons is important for this research, as in the case of diffraction and total atomic scattering [1]. Where the importance of the subject in the find of optical properties of metals as mentioned in the research board and its applications in laser systems and all optical systems, the attenuation of X-rays in different materials provides a wide range of information about the fundamental properties of matter at the atomic and molecular level.…”
