Isomeric transition

Isomeric transition is a process where an excited atomic nucleus releases energy by changing its internal structure without emitting particles. Instead, it emits a gamma ray—high-energy electromagnetic radiation—similar to a powerful light wave. This transition occurs when the nucleus shifts from a higher-energy state to a lower-energy state, stabilizing itself. It’s a common way for radioactive atoms to shed excess energy, and it helps scientists understand nuclear properties. Think of it as the nucleus “relaxing” by emitting a gamma ray, much like how an excited atom might emit light when returning to a lower energy level.
