Gamma Ray Creation

Animations by Susan Twardy Released on September 7, 2007
Gamma rays are the highest-energy forms of light in the electromagnetic spectrum and they can have over a billion times the energy of the type of light visible to the human eye. 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).
