The Spectrum of Scattered X-Rays

  • Decide which spectral line is coherent scattering and which is Compton scattering.
  • Choose which angle θ to analyze.
  • Estimate the angle ϕ of each spectral peak from the data.
  • Approximate the uncertainty in the estimation of ϕ.
  • Convert the values of ϕ from degrees/minutes to decimal degrees.
  • Determine the wavelength for each angle using Bragg’s law.
  • Calculate the wavelength shift.
  • Relate the wavelength shift to the Compton wavelength.
  • Compute the Compton wavelength.
  • Propagate the uncertainty.
  • Convert from Ångstroms to nanometers.
