#### 6.1.1.1. Coherent (Rayleigh) scattering

| top | pdf |

An electromagnetic wave incident on a tightly bound electron is scattered coherently. For an incident wave of unit amplitude with the electric vector normal to the plane of the reflection x0y containing the incident and diffracted beams (Fig. 6.1.1.1 ), the amplitude of the scattered wave at a distance r is where is the classical radius of the electron (2.818 × 10−15 m).

 Figure 6.1.1.1 | top | pdf |Scattering by an electron. k0 and k are the incident and scattered wavevectors, respectively.

For a wave with the electric vector parallel to the plane x0y, the amplitude of the scattered wave is For unpolarized incident radiation with unit mean amplitude, the amplitude of the scattered wave is given by the Thomson formulaThe corresponding intensity of scattering per unit solid angle is for an unpolarized incident beam of intensity .

#### 6.1.1.2. Incoherent (Compton) scattering

| top | pdf |

For scattering from a free electron, the quantum nature of the radiation must be considered. Under the impact of a photon with energy hc/λ, momentum h/λ, the recoil of an electron, initially at rest, results in a change in wavelength of a geometry similar to that in Fig. 6.1.1.1 being assumed. There is no fixed relationship between the phases of the incident and scattered beams – i.e. the scattering is incoherent. The intensity predicted by the Thomson formula is modified by the correction factor [λ/(λ + Δλ)]3.

#### 6.1.1.3. Atomic scattering factor

| top | pdf |

For scattering by atomic electrons there are both coherent and incoherent components, with total intensity given by the Thomson formula. The phase for coherent scattering is by convention related to that of a free electron at the nucleus. There is a phase shift of π for scattering from a free electron. The scattering from an element of electron density has a phase difference of , where The total amplitude for coherent scattering from the jth electron is The intensity of coherent scattering is The intensity of Compton scattering from that electron is For an atom with atomic number Z, and where the correction term owing to exchange, meets the requirements of the Pauli exclusion principle.

Atomic scattering factors for neutral atoms are listed in Table 6.1.1.1 for the range . The values for hydrogen are calculated from the analytical solution to the Schrödinger equation and are effectively zero for . Those for heavier atoms are for relativistic wavefunctions, based on the calculations of Doyle & Turner (1968) using the wavefunctions of Coulthard (1967) (designated RHF in Table 6.1.1.1), or on those of Cromer & Waber (1968) using the wavefunctions of Mann (1968a) (designated *RHF). The latter are based on a more exact treatment of potential that allows for the finite size of the nucleus, but the effect on the scattering factors is small. The calculations of Cromer & Waber (1968) were originally made for , but these have been extended to 6 Å−1 by Fox, O'Keefe & Tabbernor (1989); this has been done because there are increasing numbers of applications for high-angle scattering factors.

For a detailed study of the effect of changes in the electron density due to chemical bonding and lattice formation, a more general procedure is necessary, as described in Subsection 6.1.1.4. The changes due to chemical bonding are small in absolute terms, and are relatively small except in the case of hydrogen.

A more approximate treatment is adequate for many purposes. An isotropic approximation to the scattering factor for bonded hydrogen, based on an analysis of the hydrogen molecule by Stewart, Davidson & Simpson (1965), is listed in Table 6.1.1.2.

Scattering for ionic models of solids may be related to the scattering factors for the corresponding free ions. Values for some of the more chemically significant ions are listed in Table 6.1.1.3. For H, Li+ and Be2+ these are based on the correlated electron calculations of Thakkar & Smith (1992). For other ions lighter than rubidium, values are based on the Hartree–Fock calculations of Cromer & Mann (1968), using the wavefunctions of Mann (1968b). For the heavier ions, the calculations are by Cromer & Waber (1968), based on relativistic Dirac–Slater wavefunctions, which are a good approximation to the corresponding relativistic Hartree–Fock wavefunctions. If ionic scattering factors are required for values of greater than those shown in Table 6.1.1.3, the free-atom scattering factors of Table 6.1.1.1 can be used because high-angle scattering is dominated by core electrons and is therefore very little affected by ionicity.
