Nuclear reaction

In nuclear physics, a nuclear reaction is a process in which two nuclei or nuclear particles collide, to produce different products than the initial particles.

In principle a reaction can involve more than two particles colliding, but such an event is exceptionally rare.

If the particles collide and separate without changing, the process is called an elastic collision rather than a reaction.

A nuclear reaction can be represented by an equation similar to a chemical equation, and balanced in an analogous manner.

Nuclear decays can be represented in the same way.
