«When a nucleus can't take in any more neutrons, it will undergo beta decay, which converts a neutron in the nucleus into a proton, while releasing an electron and a lightweight particle called an anti-neutrino.
A common decay mode happens when a neutron inside the nucleus emits an electron (called a «beta») and an antineutrino to become a proton.
«Our experiment seeks to observe a phenomenon called «neutrinoless double - beta decay» in atomic nuclei.
In a radioactive metamorphosis called single beta decay, a neutron (a neutral particle) in the nucleus of an unstable atom spontaneously turns into a proton (a positive particle) and emits an electron and an antineutrino — the antimatter twin of a neutrino.
Physicists had been puzzling over something called radioactive beta decay, in which one kind of atom changes into another.
But Daya Bay's nuclear reactors produce billions of trillions of electron antineutrinos every second, emitted by neutrons during a process called «beta decay,» and scientists have finally been able to measure their metamorphosis as they pass through a series of detectors positioned outside the reactors.
The aim is to use the detector to try to observe a theoretical atomic event called neutrinoless double - beta decay — a radioactive process whereby an atomic nucleus releases two electrons and no neutrinos.
New project is aimed at detecting a process called neutrinoless double - beta decay, which could be key to explaining why there is more matter than anti-matter in the universe.
Six years after the discovery of radioactivity (1896) by Henri Becquerel of France, the New Zealand - born British physicist Ernest Rutherford found that three different kinds of radiation are emitted in the decay of radioactive substances; these he called alpha, beta, and gamma rays in sequence of their ability to penetrate matter.
