What Happens When Two Gamma Rays Collide? | Exploring Pair Production
Discover the fascinating process of pair production in gamma ray collisions—how energy transforms into matter at a subatomic level.
29 views
When two gamma rays collide, they can produce a particle-antiparticle pair, such as an electron and a positron. This process is called pair production and requires sufficient energy, generally more than 1.022 MeV. Such collisions are extremely rare and are typically studied in high-energy physics and astrophysical contexts.
