Explain the features of the Compton effect:
a) necessity to use a sufficiently short wavelength X-rays to check the formula of Compton shift;
b) independence of the magnitude of shift from the kind of substance;
c) existence of a undisplaced component in scattered radiation;
d) increase of the intensity of shifted component of scattered radiation with the decrease of material atomic number , as well as with the increase of scattering angle;
e) broadening of both of the components of scattered radiation.
