Transition Energy

Definition

Transition energy refers to the specific amount of energy required for a particle to change from one state to another, such as moving between energy levels in an atom or transitioning between different particle states in high-energy physics. This concept is crucial when understanding particle interactions, decay processes, and the mechanisms involved in particle acceleration, as it determines how particles can be manipulated and studied.
