After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray.

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.

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 ...

Through the weak nuclear force, one quark flavor can transmute into another. However, current data and theory indicate that ...

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 ...
