Antiparticles and Photons 0.0 / 5 ? PhysicsParticle physicsASAQA Created by: akelly_3102Created on: 04-05-18 09:42 Pair production only happens when...? It only happens when there is enough energy to produce the masses of the particles. 1 of 5 What is the definition of rest energy? The amount of energy that would be produced if all of its mass was transformed into energy. 2 of 5 What are electron-positron pairs formed from? A high energy photon. 3 of 5 Why are electron-positron pairs more commonly produced? Because they have a relatively low mass. Low mass means low rest energy so less energy is needed for pair production to happen. 4 of 5 What happens when matter and antimatter annihilate? All of the mass of the particle and the antiparticle gets converted back to energy as two gamma ray photons. 5 of 5
