He knew the power and results of the green beam of atomic decay that he would give his forces to use.

But as the rifle came up to his shoulder, he was back inside his own head, calculating as abstractly as if he were working on a problem of atomic decay.

The pions undergo atomic decay into neutrinos and muons.

For though they had no timepiece, there was a process going on that was measuring time as surely as atomic decay: Valiha was making a baby Titanide.

For instance, quantum mechanics allows a very precise calculation of the half-lives of atoms even though the process of atomic decay is random.

They do not rely on atomic decay.

But sure as atomic decay - and just as predestined - the police reach out and pull them in.

Along the chain of consequence, from atomic decay to my act of observation, things must have got fixed at least by the time that the cat's experience entered into it.

And if the atmosphere also failed to support anaerobic life-forms, there'd be little within the barrier to cause decay except sunlight, cosmic radiation, and atomic decay.

There has been damage to my memory-forty million years of atomic decay and cosmic radiation has scarred me.
