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].
