Gamma rays can be created in several different ways: a high-energy particle can collide with another particle, a particle can collide and annihilate with its anti-particle, an element can undergo radioactive decay, or a charged particle can be accelerated. In this animation, we see a high-energy photon collide with a free electron, which causes the creation of a gamma-ray.    This animation shows a high-energy photon (blue coil) colliding with a free electron (red ball), which causes the release of a gamma-ray (purple flash).
