Show that when a photon of energy E is scattered from a free electron at rest, the maximum kinetic energy of the recoiling electron is given by:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]K_{max} = \frac{E^2}{E + mc^2/2}[/tex]

This a "Compton effect" problem.

The kinetic energy of the electron is given by:

[itex]K = E - hf'[/itex] where f' is the frequency of the scattered photon. But this doesn't even remotely resemble the result I need. Am I missing out on something?
