Compton ScatteringWith Bragg crystal spectrometer technique,X-ray sources with definite energy can beused for precise experiment.X-ray sourceCollimator(selects angle)Crystal (selectswavelength)A. H. ComptonTargetθDetectorA.H. Compton, Phys.Rev. 22 409 (1923)Result: peak in scattered X-ray radiation shifts to lowerenergy (longer wavelength) than the source. The amount ofshift depends on θ (but not on the target material).57
