Nuclear 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 کاملDouble Beta Decay and the Absolute Neutrino Mass Scale
The marvelous recent results of neutrino oscillation experiments have given us important information on neutrino mixing. The data of solar neutrino experiments and of the KamLAND long-baseline ν̄e disappearance experiment show νe → νμ ,ντ transitions generated by the squared-mass difference ∆mSUN in one of the two ranges [1] 5.1×10−5 < ∆mSUN < 9.7×10 −5(LMA-I) , 1.2×10−4 < ∆mSUN < 1.9×10 −4(LMA-...
متن کاملNeutrinoless Double Beta Decay - and the Neutrino Mass Matrix
Double beta decay is indispensable to solve the question of the neutrino mass matrix together with ν oscillation experiments. Recent analysis of the most sensitive experiment since eight years the HEIDELBERG-MOSCOW experiment in Gran-Sasso yields evidence for the neutrinoless decay mode. This result is the first evidence for lepton number violation and proves the neutrino to be a Majorana parti...
متن کاملNuclear 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 کاملOn the Neutrino Mass Spectrum and Neutrinoless Double - Beta Decay
Assuming 3-ν mixing, neutrino oscillation explanation of the solar and atmospheric neutrino data and of the first KamLAND results, massive Majorana neutrinos and neutrinoless double-beta ((ββ) 0ν-) decay generated only by the (V-A) charged current weak interaction via the exchange of the three Majorana neutrinos, we analyze in detail the possibility of determining the type of the neutrino mass ...
