Nuclear structure and double beta decay
Study of the neutrinoless double beta decay, 0νββ, includes a variety of problems of nuclear structure theory. They are reviewed here. The problems range from the mechanism of the decay, i.e. exchange of the light Majorana neutrino neutrino vesus the exchange of some heavy, so far unobserved particle. Next, the proper expressions for the corresponding operator are described that should include ...
متن کاملNuclear structure and double beta decay: Two neutrino mode.
The decay rate of the 2v double beta decay is calculated. The effects of pairing, static quadrupole deformation, spin-isospin polarization, and the .6.33 isobar admixtures on the nuclear matrix elements are studied and the relation of the 2v {3{3 rate and the {3and f3+ strength is stressed. In agreement with other calculations, we predict a faster decay rate than has been observed experimentall...
متن کاملNuclear Physics of Double Beta Decay
Study of the neutrinoless ββ decay allows us to put a stringent limit on the effective neutrino Majorana mass, a quantity of fundamental importance. To test our ability to evaluate the nuclear matrix elements that govern the decay rate, it is desirable to be able to describe the allowed two-neutrino decay. It is argued that only low-lying virtual intermediate states are important for that proce...
متن کاملNuclear physics aspects of double beta decay
— Comprehensive description of the phenomenology of the ββ decay is given, with emphasis on the nuclear physics aspects. After a brief review of the neutrino oscillation results and of motivation to test the lepton number conservation, the mechanism of the 0νββ is discussed. Its relation to the lepton flavor violation involving charged leptons and its use as a diagnostic tool of the 0νββ mechan...
متن کاملNuclear moments for the neutrinoless double beta decay II
The recently developed formalism for the evaluation of nuclear form factors in neutrinoless double beta decay is applied to Ca, Ge, Se, Mo Te and Te nuclei. Explicit analytic expressions that follows from this theoretical development, in the single mode model for the decay of Ca, have been worked out. They are useful both for testing the full numerical calculations, and to check analytically th...
