“…It exploits the similarity between the Fermi part of the neutrino potential in 0νββ decay and the radial dependence of the Coulomb interaction. The latter is well-known to be the leading source of the isospin breaking in nuclei [42,43]. As shown in Ref.…”

A new generation of neutrinoless double beta decay (0νββ-decay) experiments with improved sensitivity is currently under design and construction. They will probe inverted hierarchy region of the neutrino mass pattern. There is also a revived interest to the resonant neutrinoless doubleelectron capture (0νECEC), which has also a potential to probe lepton number conservation and to investigate the neutrino nature and mass scale. The primary concern are the nuclear matrix elements. Clearly, the accuracy of the determination of the effective Majorana neutrino mass from the measured 0νββ-decay half-life is mainly determined by our knowledge of the nuclear matrix elements. We review recent progress achieved in the calculation of 0νββ and 0νECEC nuclear matrix elements within the quasiparticle random phase approximation. A considered self-consistent approach allow to derive the pairing, residual interactions and the two-nucleon short-range correlations from the same modern realistic nucleon-nucleon potentials. The effect of nuclear deformation is taken into account. A possibility to evaluate 0νββ-decay matrix elements phenomenologically is discussed.

“…For example, proton strength in a valence s 1/2 orbital produces a Thomas-Ehrman shift [22] decreasing ∆E C . While this physics is not applicable to the first excited state of 9 C, it is worth considering the possibilities for the 9 C 4.40 -9 B 19.254 pair where the emission of a s 1/2 proton could also explain the large widths of these states.…”

“…Auerbach chose V 1 = 100 MeV, ξ = 3, andhω = 41A −1/3 MeV and estimated 2 1 by appealing to a number of "gross" models discussed in Ref. [17]: a hydrodynamical model, models based on non-energy-weighted and energy-weighted sum rules, and a microscopic model. Each enabled him to obtain a simple expression for δ C as a function of the mass number A.…”

Comparative tests of isospin-symmetry-breaking corrections to superallowed0+→0+nuclearβdecay

We present a test with which to evaluate the calculated isospin-symmetry-breaking corrections to superallowed 0 + → 0 + nuclear β decay. The test is based on the corrected experimental Ft values being required to satisfy conservation of the vector current (CVC). When applied to six sets of published calculations, the test demonstrates quantitatively that only one set, the one based on the shell model with Saxon-Woods radial wave functions, provides satisfactory agreement with CVC. This test can easily be applied to any sets of calculated correction terms that are produced in future.
