One hundred years later many physicists around the world are involved in studying the consequences and use as a research tool, of the deflection of light by gravitational fields, a discipline. Distribution du diamtre dentre des pores a zoom b 105 figure 52. By contrast, inelastic scattering occurs when energy is transferred from the incoming x ray to the crystal, e. Xray diffraction is a versatile, nondestructive analytical technique for identification and quantitative determination of the various crystalline forms, known as phases, of compounds present in powdered and solid samples. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a threedimensional picture of the density of electrons.
