Alpha radiation is made up of a stream of alpha ... but the electron is ejected at high speed. This is called beta decay. Beta decay causes the atomic number of the nucleus to increase by one ...

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 ...

In beta decay, a proton or neutron in a nucleus emits ... the energies and directions of the emitted beta particle and two alpha particles with high precision. This approach allowed the ...

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 ...
