Classical Scattering from an Electron

For a beam polarized in an arbitrary direction its electric field vector Eq can be decomposed into its Y and Z components as in [Pg.11]

The flux of energy reaching a unit area per second at P is proportional to E2 = (E2) + (E2) and is therefore given by [Pg.11]

This is called the Thomson formula for the scattering of x-rays by a single electron. [Pg.12]

The factor e1 mc1 in (1.35) has dimension of length and is called the classical radius of the electron, re. Its numerical value is 2.818 xl0 15 m. The physical fact embodied in (1.35) can be expressed in an alternative language. Thus, the differential scattering cross section of an electron for unpolarized x-rays is [Pg.12]

By integrating (1.36) throughout the solid angle Q, that is, over (= 20) from 0 to 7r and over O from 0 to 2n [cf. Equation (1.12)], we find the total scattering cross section of an electron to be [Pg.12]
