Klein-Nishina formula

The Klein-Nishina formula describes how high-energy photons, like X-rays or gamma rays, scatter off electrons. It explains how the photons lose energy and change direction during this interaction, depending on their initial energy. The formula accounts for relativistic effects, meaning it accurately predicts scattering behavior at very high energies. It’s fundamental in understanding processes in astrophysics, medical imaging, and radiation physics. Essentially, it allows scientists to calculate how much energy photons transfer to electrons when they collide, helping us understand the behavior of radiation in different environments.
