How to make a gamma ray
A series of animations showing how gamma rays can be created through various particle interactions.
Pion production and decay animation. A proton travelling to the speed of light strikes a slower-moving proton. The protons survive the collision, but their interaction creates an unstable particle — a pion — with only 14 percent of the proton's mass. In 10 millionths of a billionth of a second, the pion decays into a pair of gamma-ray photons.
