Sentences with phrase «radioactive beta decay»

Things in life that are slow: snails, molasses, an iceberg, the radioactive beta decay of certain isotopes... and sometimes, relationships.

Physicists had been puzzling over something called radioactive beta decay, in which one kind of atom changes into another.

In the 1920s, for instance, radioactive beta decay perplexed many physicists because it seemed not to obey the law of conservation of energy.

Not exact matches

Wu was the first to verify — and later refine — Enrico Fermi's theory of radioactive beta - decay, which describes how some unstable atoms emit radiation when transforming into more stable atoms.

Neutrinoless double beta decay is a variation on standard beta decay, a relatively common radioactive process that occurs naturally on Earth.

This explains why it took researchers nearly 30 years to catch a first glimpse of neutrinos, although their existence had been first postulated in 1930 to explain an apparent violation of the conservation of energy in the radioactive decay of unstable atomic nuclei known as beta decay.

The radioactive decay of radon gas produces alpha particles (consisting of two protons and two neutrons, an alpha particle is just the bare nucleus of a helium atom), beta particles (which are actually fast - moving electrons), and gamma rays (very energetic photons).

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.

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.

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.

In nuclear physics, beta decay (β - decay) is a type of radioactive decay in which a beta ray (fast energetic electron or positron) and a neutrino are
