Reviews of Modern Physics, 1978
The problem of double beta decay is reviewed with emphasis on its relevance to lepton number conservation. Recently, the ratio of the double beta-decay half-lives of $^{128}\mathrm{Te}$ and $^{130}\mathrm{Te}$ has been measured in a geological experiment and a limit for the ratio of the neutrinoless rate to the total rate for $^{82}\mathrm{Se}$ decay ...

Reports on Progress in Physics, 1991
Developments in the theoretical investigation of nuclear double-beta decay are reviewed. In particular, the neutrinoless mode is discussed in detail, since it is sensitive to lepton number violation as predicted by gauge theories beyond the standard model and it is expected to give important information on the nature of the neutrinos and the weak ...

Reports on Progress in Physics, 1959
The phenomenon of double beta decay is discussed rather fully both from the experimental and from the theoretical point of view, the relation between double beta decay and the possible kinds of inverse beta decay being also briefly treated. A summary of the available experimental data is given, all methods of detection of the various double beta decay ...

Il Nuovo Cimento A, 1977
In this paper we study the double-beta-decay process in order to test the existence of an electronic lepton number conservation law. We give general formulae for the transitions 0+ → 0+, 0+ → 2+, 0+ → 4+ for neutrinoless double beta-decay. The double beta-decay of48Ca is studied in detail. From the experimental data we conclude that |δ − 1| ≤3·10−6.

AIP Conference Proceedings, 2007
The subjects of the two‐neutrino (2νββ) and neutrinoless double beta (0νββ) decays are introduced. The main theoretical and experimental issues related to the double beta decay are discussed. It is stressed that the study of the 0νββ decay is the most important source of information about the Majorana nature of neutrinos.

Physics Bulletin, 1988
Double beta decay is the radioactive disintegration, in a single jump, of a nucleus with atomic number Z and mass number A to the nucleus with atomic number Z + 2 . During this process the mass number is unchanged as two neutrons transform into protons and the nucleus emits two beta particles; the decay is possible for certain nuclei for which ordinary

In a double-beta event, two neutrons decay simultaneouly into two protons, two beta rays (electrons) and two antineutrinos. Experimentalists are now searching for another form of double-beta decay, one that does not produce neutrinos or antineutrinos. If such an event is found, it could unravelone of nature's great mysteries: What, if anything, is the ...

In the last few years our understanding of neutrino intrinsic properties has expanded in a revolutionary and unexpected way. The results of experiments with solar, atmospheric, reactor, and accelerator neutrinos are all (or almost all) consistent and lead to the inescapable conclusion that neutrinos are massive but very light particles and that they ...
