Which process releases gamma radiation during a nucleus rearrangement?

• A. Alpha decay
• B. Nuclear fission
• C. Gamma radiation
• D. Nuclear fusion

Answer: (C)

When a nucleus finishes a reaction or decay, it often sits in an excited energy state. To drop to a lower energy level, it can emit a high-energy photon called a gamma ray. This emission carries away the excess energy without changing the number of protons or neutrons, so the nucleus’s identity stays the same while its energy state rearranges. In contrast, alpha decay ejects an actual particle (an alpha particle), nuclear fission splits the nucleus into smaller pieces (often with neutrons released), and nuclear fusion combines light nuclei. These latter processes involve particle emission or changes in composition, whereas the gamma-ray emission specifically reflects de-excitation of the nucleus. So the process releasing gamma radiation during a nucleus rearrangement is the gamma radiation itself.
