Principle

Photons of the molybdenum Kα X-ray line are scattered at the quasi-free
electrons of an acrylic glass cuboid. The energy of the scattered
photons is determined in an angle-dependent manner with the aid of
a swivelling semiconductor detector and a multi-channel
analyser.

Tasks


Energy calibration of the multi-channel analyser with the aid
of the two characteristic molybdenum X-ray lines Kα and Kβ.

Energy determination of the photons of the Mo-Kα-line that are scattered through an acrylic
glass element as a function of the scattering angle.

Comparison of the measured energy values of the lines of
scatter with the calculated energy values.

Calculation of the Compton wavelength of electrons and a
comparison of this value with the corresponding value of the 90°
scattering.
