23 results about "Positron annihilation" patented technology

Electron–positron annihilation occurs when an electron ( e −) and a positron ( e +, the electron's antiparticle) collide.At low energies, the result of the collision is the annihilation of the electron and positron, and the creation of gamma ray photons: . e − e + γ + γ. At high energies, other particles, such as B mesons or the W and Z bosons, can be created.
