Silver-110’s decay reveals a promising path to measure antineutrino mass. New data could reshape future neutrino studies.

The approach uses techniques from organic chemistry, optical microscopy, and nuclear physics to identify individual barium ...

In beta decay, a proton or neutron in a nucleus emits a beta particle (an electron or its anti-particle, a positron) and a neutrino. The properties of the beta decays of the radioactive mirror ...

Neutrino mass measurements remain one of the most challenging endeavours in contemporary physics. Direct measurement techniques, particularly those probing the endpoint of the tritium β-decay ...

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 ...

These electrons carry away most — but not all — of the energy released during a beta decay event. It’s that missing energy that can reveal the neutrino mass. Although this subtraction strategy has ...

Unlike tritium, holmium-163 doesn’t undergo beta decay. Instead, one of the electrons in the atom gets ‘captured’ by a proton in its nucleus. This converts the proton into a neutron ...

But if the neutrino is its own antiparticle, there’s the possibility of something even more rare than that: a double-beta decay where the two neutrinos annihilate each other immediately, leaving ...

Scientists have observed a rare new radioactive decay mode for the first time. In this decay mode, oxygen-13 (with eight protons and five neutrons) decays by breaking into three helium nuclei (an ...

For example, during the Ac-227 beta decay, a neutron emits a W – boson and turns into a proton, and the W – boson decays to an electron and an anti-neutrino. A sign in the difference ...
