Definition: Reradiating is a concept in quantum mechanics, particularly related to particle physics. It refers to the process of changing one state (a state that represents a particle) into another state (a state that represents its inverse). This can be achieved through an interaction between two particles that has both positive and negative consequences for their respective states. In simpler terms, if you have a system with two different energy levels or states, reradiating it allows the system to change from one to the other by
