Here is the equation for the alpha decay of radon-219 into polonium. Beta decay involves the conversion of a down quark to an up quark. This changes a neutron into a proton plus an electron.

New experiments on thallium decay have helped determine the Sun formed over 10–20 million years, improving stellar nucleosynthesis models. Have you ever wondered how long it took our Sun to form in ...

The observation of neutrinoless double beta decay could have important implications for the study of matter and antimatter. In fact, it would confirm that neutrinos and their antiparticles (i.e ...

The measured bound-state beta decay half-life is essential to analyzing the accumulation of ²⁰⁵Pb in the interstellar medium. However, other nuclear reactions are also important, including ...
