Neutrinos and antineutrinos are elementary particles with small but unknown mass. High-precision atomic mass measurements at ...

Beta (\(\beta^-\)) decay is the release of an electron by the change of a neutron to a proton. The neutron (charge = 0) is made up of one up quark (charge = \(\frac{2}{3}\)) and two down quarks ...

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.

The effects of the weak force were first discovered at the turn of the 20th century, in the place where it is most obviously at work: in radioactive beta decay. In the most common form of this ...

As Surrey’s Matthew Williams explains, the standard picture is that these elements were formed when other elements captured neutrons, then underwent beta decay. The two ways this can happen are known ...

nEXO will search for neutrinoless double beta decay of xenon-136. Neutrinoless double beta decay experiments probe physics beyond the Standard Model by searching for an extremely rare nuclear decay.

KATRIN utilizes the beta decay of tritium, an unstable hydrogen isotope, to assess the mass of neutrinos. The energy distribution of the electrons resulting from the decay enables a direct ...
