When a high-energy gamma-ray photon passes near an atomic nucleus, it can disappear and produce an electron and its antimatter partner, a positron. The nucleus takes up the recoil needed to conserve momentum, while the photon’s energy supplies the pair’s mass and motion. The minimum energy is about 1.022 MeV: enough for the rest energy of one electron plus one positron. Any extra energy becomes kinetic energy. This process is called pair production, and it reveals a remarkable fact about E = mc²: matter can be created from light when energy and momentum are both accounted for. 🔔 Subscribe for more lectures that make you think differently. 📚 SOURCES: • International Atomic Energy Agency — Nuclear Medicine Physics, §1.6.8 “Pair production”: https://www-pub.iaea.org/mtcd/publica... • Particle Data Group — Review of Particle Physics, “Passage of Particles Through Matter”: https://pdg.lbl.gov/2023/reviews/rpp2... • Feynman, R.
