The neutrino was first postulated in 1931 by Wolfgang Pauli to explain the energy spectrum of beta decays, the decay of a neutron into a proton and an electron. Pauli theorized that an undetected particle was carrying away the observed difference between the energy and angular momentum of the i...
neutrino and gamma astronomycosmological neutrinosWe study the interaction of low energy neutrinos on nuclei that spontaneously undergo beta decay showing that the product of the cross section times neutrino velocity takes values as high as 10^{-42} cm^2 c for some specific nuclei that decay via...

Earlier (in 1930) Pauli had used the term "neutron" for both the neutral particle that conserved energy in beta decay, and a presumed neutral particle in the nucleus; initially he did not consider these two neutral particles as distinct from each other.[16] The word "neutrino" entered the...
Neutrinoless double beta decay (0νββ) is one of the most sensitive probes for physics beyond the Standard Model, providing unique information on the nature of neutrinos. In this paper we review the status and outlook for bolometric 0νββ decay searches. We summarize recent advances in ba...
In 1934, he based a theory of beta decay to include the neutrino (All 1). They were also referred to them as “ghostly” because of their properties. Because of this, they had to wait about 25 years after these unknown particles were introduced in order for there to be the first ...
Calibration of the detector is required to determine, in both detectors, the efficiency for observing the inverse beta decay reaction, the energy scales for positrons, neutrons and gamma, the timing of the photomultipliers and the light transport properties. To this end gamma sources, neutron sourc...
The neutrino was first proposed as the neutral accompanying particle emitted in beta decay. There has been great interest in determining the mass of the neutrino because the cumulative neutrino mass may account for the “missing mass” in the universe, with great cosmologic implications. More ...
Cosmic neutrinos may be produced either in the vicinity of the cosmic-ray source or along the cosmic-ray propagation path, leading to the production of secondary unstable particles, which subsequently decay into neutrinos. Cosmic rays interacting in the Earth’s atmosphere produce atmospheric neutrinos...
Neutrinoless double beta decay experiments seek to determine the nature of the neutrinos as Majorana or not. These experiments have so far set limits on the effective electron neutrino mass [76] , where withUrepresenting . In all the four mixing scenarios predicted by the model, Eqs. (35), ...
