The two main mechanisms by which X-rays interact with matter
are via Compton scattering and absorption by the photoelectric
effect. By referring to the dependence of these effects on X-ray
energy, explain what happens to X-ray image quality when using
excessively high tube voltages?

In a Compton scattering experiment, an incident photon of energy
295.00 kev scatters off a loosely bound electron resulting in the
scattered photon to have an energy of 159.00 kev.

An photon with a wavelength in the X-ray region of 0.69 nm
undergoes Compton scattering by colliding with a free electron. 1)
Assume the photon just barely grases the electron, so that the
deflect angle, θ, can be considered zero.
1)What is the wavelength of the outgoing photon after the
collision? λ' =
2)What the energy of the outgoing photon? Eγ

3)Now assume the photon deflects off at a small angle of
49o. What is the wavelength of the...

Measurements of the photon energy (E) from a Compton scattering
experiment show two peaks: one at higher energies for the source
gamma rays (GR), and another at lower energies for the scattered
photons (SP). Each peak is expected to obey a Gaussian
distribution; e.g. for the scattered photons: SP = ASP
exp(-((E-ESP)/WSP)2), where
ASP is the amplitude, ESP the peak energy,
and WSP the peak width; with a similar equation and set
of parameters for the GR. The table (below)...
