X-ray emission spectra are usually excited by X-ray photons because most chemical compounds are decomposed by electron bombardment. With X-ray emission spectra excitation by photons [secondary emission or fluorescence (XFS)] the fluorescent line intensity depends on the excitingphoton energyhν andIi...
Gamma photons of energy 59.54 keV from an Am-241 radioactive source are used to excite K and L X-ray photons of various energies. By measuring the intensities of incident and transmitted X-ray photons in Sn foil with a good geometry arrangement, the K shell photoelectric cross sections are...
since the energy of X-ray is very high compared with UV radiation, a significant number of electrons excite to the CB during X-ray radiation. As a result, current is found to flow through the external circuit at relatively low bias voltage. The I-V characteristic under X-ray radiation is...

The effective cross section due to the presence of the electron in the K-shell is given by: σre = 4πre2 (20) The previous cross section is the result of interference between the atomic nucleus and an electron in the K-shell, after an X-ray is reflected from the nucleus surface. ...
