Article No: P2546005
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. 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.
