beta decay

a type of radioactivity that results in the emission of beta particles, either electrons or positrons. See also beta particle.

beta decay

Low-level radioactive decay in which particles, usually an electron with an antineutrino, or less commonly a positron with an antineutrino, are emitted.

It seems intuitive to me, and I hope to the reader, that postulating seventeen million neutrinos in each case of Beta decay produces a theory that is less plausible and attractive than the theory proposed by Pauli and Fermi.
When an atom undergoes beta decay, it converts a neutron to a proton.
It starts with introductory concepts (such as the atom and modern physical concepts), then describes nuclear properties, radioactive decay kinetics, radiotracers, nuclear forces, nuclear structures, alpha decay, beta decay, nuclear reactions, fission, nuclear reactions in nature such as in nuclear astrophysics, analytical applications of nuclear reactions, reactors and accelerators, the transuranium elements, nuclear reactor chemistry, interaction of radium with matter, radiation detectors and radiochemical techniques.
As the trapped neutrons beta decay, the resulting energetic electrons generate scintillations in the liquid He.
Objective: Neutrinoless double beta decay (0) is considered the best potential resource to determine the absolute neutrino mass scale.
In beta decay an unstable nucleus emits an electron (labeled a beta particle before anybody knew what it really was).
In this graduate-level text, Lipkin (The Weizmann Institute of Science, Israel) describes the aspects of beta decay that can be understood without reference to the formal theory about the reactions that follow directly from conservation laws and elementary quantum mechanics.
Beta decay of the neutron is both the simplest nuclear beta decay and the simplest of the charged-current weak interactions in baryons.
Tenders are invited for applications for research and development that will allow existing technology candidates to demonstrate down-selection criteria for the next generation of neutrinoless double beta decay measurements.
The spectrometer and methods we have developed provide means to control systematic errors never before available in the study of neutron beta decay.
MASS DELUSION Neutrinos were first inferred to exist in 1930 to account for missing energy in a nuclear disintegration process known as beta decay.
Objective: Neutrinoless double beta decay is a hypothetical, very slow radioactive process whose observation would establish unambiguously that massive neutrinos are Majorana particles that is to say, identical to their antiparticles , which implies that a new physics scale beyond the Standard Model must exist.
