The most plausible candidates responsible for the hypothetical solar-induced cycles in the decay series of 222Rn would be the beta emitters 214Pb and 214Bi, since their decay is followed by significant gamma-ray emission. They are short-lived (27 min and 20 min) such that decay formulas (...
Measurement of these beta particles in a time projection chamber with a perpendicular magnetic field provides a distinctive set of systematic considerations for comparison to the original seminal beta spectra measurements. Ancillary measurements such as gamma-ray emission and post-irradiation radiochemical ...
The study of beta decay provided the first physical evidence for theexistence of the neutrino. Thediscovery of the neutrinois based on thelaw of conservation of energyduring beta decay. The resulting particle (alpha particleorphoton) has anarrow energy distribution in both alpha and ...

process, referred to as beta decay, results in some circumstances in the emission of beta radiation. Beta decay may be defined as any nuclear decay process whereby the mass number (A) of the nucleus remains the same and the atomic number (Z) changes. There are three main types of beta ...

tritium measure that of the anti-neutrino\(\bar{\nu }\). New ideas exist to extend the sensitivity of tritium-based neutrino-mass experiments beyond the KATRIN design sensitivity by new technologies, such as cyclotron radiation emission spectroscopy and the development of atomic tritium sources21,...
History of Neutrino ExperimentsNeutrinos were first theorized to exist by Wolfgang Pauli in 1931, in order to preserve conservation of energy for beta emission. Enrico Fermi named the particle "neutrino," meaning "little neutral one" in Italian, to distinguish it from the larger neutral neutron. ...
2.3 might help in separating multi-gamma events, such as 136Cs and 130I decays, from points like events as the neutrinoless double beta decay ones. Internal contamination 214Bi (Q=3.27 MeV, U-chain) and 208Tl (Q=5 MeV, Th-chain) decays can fall in the NLDBD ROI. The targeted ...
