Absolute-scale determination of bremsstrahlung following photoabsorption of incident x and<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>γ</mml:mi></mml:math>rays

The spectrum of bremsstrahlung due to photoelectrons ejected by incident photons of energy 59.5 keV was measured on an absolute scale. A coincidence experimental setup with two high-purity germanium detectors was used. One detector served as the target as well as the detector of ejected electrons and another (second) detector served as the detector of bremsstrahlung radiation. The applied experimental method gives a very clean bremsstrahlung...
