Let's look at radioactive decays where there are transitions between states of the same nucleus from a gravity particle perspective. Much of this is taken from the page https://en.wikipedia.org/wiki/Radioactive_decay.
1. Isomeric transition:
Excited nucleus releases a high-energy photon (gamma ray) (A, Z)
Excited basic particles in the nucleus, \(p^{+}\), \(g^{-}\), \(T^{+}\) slow down, releasing gamma rays.
2. Internal conversion:
Excited nucleus transfers energy to an orbital electron, which is subsequently ejected from the atom (A, Z)
An excited \(g^{+}\) particle breaks away from the proton pair \((g^{-},\,g^{+})\), temporarily. The proton loses its charge and converts to a neutron. A electron in orbit is freed. After which the \(g^{+}\) particle is recaptured and the neutron reverts to the proton pair \((g^{-},\,g^{+})\).
At this point, every explanations are just concoctions that serve more to entertain than science. None of this is vindicated. Then again, no close enough observation is possible at the subatomic level.
Much of the existing explanation is worse speculation.
