Too bad other elements do not undergo spontaneous decay to produce gold!

Some grand unified theories would require the eventual spontaneous decay of the proton.

From there on, a new Rabi oscillation will start until the next spontaneous decay.

Each spontaneous decay essentially changes the phase of the Rabi oscillation.

Several researchers, however, dispute that spontaneous decay plays any significant role in forgetting over the short-term, and the evidence is far from conclusive.

Extra souls are forbidden, and where they occur shall undergo spontaneous decay.

The spontaneous decay of free protons has never been observed, and the proton is therefore considered a stable particle.

The lifetime for spontaneous decay is very long, so we do not see this decay process happening around us.

Well, that could cause spontaneous decay in certain tissues.

Lifetimes must be long enough that doses from the spontaneous decay from the targets always remain within safe limits.
