= Compton wavelength shift
{c}
{title2=$\Delta\lambda=\lambda_C(1-\cos\theta)$}

For a photon scattered through angle $\theta$ by an initially stationary free <electron>, exact relativistic <conservation of energy> and <conservation of momentum> give $\lambda\prime-\lambda=(h/m_ec)(1-\cos\theta)$. Backscatter gives the maximum shift, $2h/(m_ec)$, independent of the initial photon wavelength.
