 Stopping power

The mean energy lost by a charged particle per unit path length through a material, with the particle species, material and energy specified. It is distinct from the particle range obtained by following the particle until it stops.

Stopping power generally refers to the ability of a material to slow down or stop a projectile, such as a bullet or a particle, as it passes through the material. The concept is used in various fields, including physics, materials science, and ballistics, and can refer to different scenarios depending on the context. 1. **In Particle Physics**: Stopping power refers to the energy loss of charged particles (like electrons or ions) as they travel through matter.
