What is double beta decay

In the well-understood process of beta decay, a nucleus emits an electron and a neutrino, while the nucleus itself is transmuted (it loses a neutron and gains one positive electric charge). Double beta decay is more exotic and occurs in just a few naturally occurring radioactive isotopes. Here, two electrons and two neutrinos are emitted by the isotope.

What is double beta decay

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 processes being considered. The theory of.

What is double beta decay

Double-beta decay is the rarest known kind of radioactive decay; it has been observed for only 12 isotopes, and all of them have a mean lifetime of more than 10 19 yr. For some nuclei, the process occurs as conversion of two protons to neutrons, with emission of two electron neutrinos and absorption of two orbital electrons ( double electron capture ).

What is double beta decay

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 interaction.

What is double beta decay

The neutrinoless double beta decay can yield the neutrino mass, if the neutrino is a Majorana particle. In the Standard Model, the neutrinoless double beta decay is not allowed but it is allowed.

What is double beta decay

In nuclear physics, double beta decay is a type of radioactive decay in which two neutrons are simultaneously transformed into two protons, or vice versa, inside an atomic nucleus.As in single beta decay, this process allows the atom to move closer to the optimal ratio of protons and neutrons.As a result of this transformation, the nucleus emits two detectable beta particles, which are.

What is double beta decay

The future experiments being assembled or proposed to search for Double Beta Decay are presented and discussed with peculiar focus on the searches for the neutrinoless channel. Extension to larger masses of experiments presently running with conventional detectors is considered. Special attention is devoted to new techniques, which could allow to overcome the limitation of the presently.

What is double beta decay

Neutrinoless double-beta decay is a decay mode of an atomic nucleus in which two neutrons convert to two protons and two electrons. This process has not been observed, and it is not known whether it exists. If this decay occurs, the neutrino is its own antiparticle, or a Majorana particle. The observation of neutrinoless double-beta decay would determine whether the neutrino is a Majorana.
