Compute the Compton wavelength shift of X-rays scattered by an electron as a function of scattering angle, for Compton-effect and photon-electron interaction analysis.
X 射线散射后波长改变量。
| Item | Formula / Note | Source / Standard |
|---|---|---|

| Maximum shift | Δλ = 2λ_C at θ = 180° | Scattering kinematics |
| Energy conservation | Derived from conservation laws | Relativistic kinematics |
| Electron recoil | Recoil electron carries energy | Detector physics |
| vs photoelectric | Partial energy transfer | Photon interactions |
