For example, protons and neutrons, the "big" particles of an atom's nucleus ... one of the pair undergoes beta decay. After that, other subsequent reactions, including the intermediate formation ...

In this decay, a lighter form of oxygen, oxygen-13 (with eight protons and five neutrons), decays by breaking into three helium nuclei (an atom without ... process called beta-plus decay.

is to look for the barium-136 nucleus that is produced by the double beta decay of xenon-136. “None of the other likely background decays would produce a barium-136 atom at the decay site,” he ...

A single atom of bismuth will last ... and the heaviest being the long-lived but unstable xenon-136, which undergoes double beta decay after around 2 × 10 21 years. Of the other eight isotopes ...

[The 18 Biggest Unsolved Mysteries in Physics] In this new study, physicists are seeking so-called neutrinoless double-beta decay ... being released from the atom. Essentially, the neutrino ...

When a radioactive atom emits an alpha particle the mass number decreases by four and the atomic number drops by two. Here is the equation for the alpha decay of radon-219 into polonium.

Two-atom systems in small traps are of fundamental interest for understanding the role of interactions in degenerate cold gases and for the creation of quantum gates in quantum information ...
