Another possibility is that a fully ionized atom undergoes greatly accelerated β decay, as observed for Re by Bosch et al., also at Darmstadt.

This forces the long-lived radioactive atoms to undergo fission, thereby producing the lighter atomic variants known as isotopes that rapidly decay to relatively harmless materials.

But Dr. Wieman's group has discovered that some kinds of parity violation can be measured very precisely from the tiny distortions cesium atoms undergo in its laser traps.

Thereafter, atoms undergo thermal motion across the surface, eventually forming bonds with other atoms.

Other atoms undergo similar changes and their photons are also different colors and characteristic.

An atom or a molecule can absorb light and undergo a transition from one quantum state to another.

In radioactive decay, the half-life is the length of time after which there is a 50% chance that an atom will have undergone nuclear decay.

When an atom undergoes nuclear fission, a few neutrons (the exact number depends on several factors) are ejected from the reaction.

When a heavy atom undergoes nuclear fission it breaks into two or more fission fragments.

Such diversity is typical of sediments whose atoms have undergone a variety of transforming processes.
