The classical x-ray
The classical plane wave representation of x-rays is:
E(r, t) = εEoei(k·r−ωt)
where ε is a unit vector in the direction of the electric field, k is thewavevector of the radiation along the propagation direction, and ω is theangular frequency of oscillation of the radiation.
If the energy, E is in keV, the relationship among these quantities is givenby:
~ω = hν = E , λν = c
λ = hc/E= (4.1357× 10−15 eV · s)(2.9979× 108 m/s)/E= (4.1357× 10−18 keV · s)(2.9979× 1018 A/s)/E= 12.398 A · keV/E to give units of A

Interactions of x-rays with matter
For the purposes of this course, we care most about the interactions ofx-rays with matter.
There are four basic types of such interactions:
1 Elastic scattering
2 Inelastic scattering
3 Absorption
4 Pair production
We will only discuss the first three.

Interactions of x-rays with matter
For the purposes of this course, we care most about the interactions ofx-rays with matter.
There are four basic types of such interactions:
1 Elastic scattering
2 Inelastic scattering
3 Absorption
4 Pair production
We will only discuss the first three.

Atomic form factor
the volume element at r contributes −roρ(r)d3r with phase factor e iQ·r
for an entire atom, integrate to get the atomic form factor f o(Q):
−ro f o(Q) = −ro∫ρ(r)e iQ·rd3r
Electrons which are tightly bound cannot respond like a free electron. Thisresults in a depression of the atomic form factor, called f ′ and a lossy termnear an ionization energy, called f ′′. Together these are the anomalouscorrections to the atomic form factor.
