This question already has an answer here:

One of the types of radioactive emissions is gamma emission. I understand how the other two types, alpha and beta, help to make the atom more stable. How exactly does gamma emission help to make the atom more stable?

When a nucleus makes an alpha or beta decay, usually it's left in an excited state. It can make the transition to lower energy state by emitting gamma rays, so in a sense, the atom is more "stable" because the nucleus is in a lower energy state.

I am not sure if this answer your question. Hope it helps.

  • $\begingroup$ I see. So gamma emissions occur only after alpha or beta decay? $\endgroup$ – Gummy bears Jun 13 '14 at 17:59

    $\begingroup$ no, the nucleus could be in an excited state for other reasons, such as having formed by nuclear fusion, or having absorbed a gamma ray previously. $\endgroup$ – DavePhD Jun 13 '14 at 18:03

The nucleus has quantized energy levels. The emission of gamma rays is a transition from a higher energy level to a lower energy level.
