Fundamentals of X-ray PhysicsThe theory of the formation of continuous and radiation and bremsstrahlung is described. Special features of a number of sources of this radiation are discussed. Special attention is given to the interaction of X-ray radiation with matter (processes of absorption, scattering, refraction and reflection). The problems of excitation of X-ray fluorescence and its dependence on a number of factor is studied. Contents 1. Characteristics of X-ray radiation 2. Bremsstrahling 3. Sources of X-ray radiation 4. Absorption of X-ray radiation. 5. Scattering of X-ray radiation 6. Refraction and reflection of X-ray radiation 7. Free electrons, formed in irradiated material and their bremsstrahlung 8.
