if you have a photon with momentum [tex] p_\gamma[/tex] traveling in the +x direction which is then deflected off a free electron and now the photon has momentum [tex]p_\gamma'[/tex] and isin the +y direction.(adsbygoogle = window.adsbygoogle || []).push({});

so the components of momentum for the electron would be

p_e = [tex]p_\gamma'[/tex] in the -y direction and for the x component

[tex]p_ex= \sqrt{p_\gamma^2-p_\gamma'^2-p_ey^2}[/tex]

does this seem like the correct approach to this problem?
