“…[26] substantially differs from the earlier estimation T f 1/2 = (1.1 ± 0.3) 10 19 years [14] (also based on SSD and measured value of electron capture rate of 116 In [27]). This result disagrees with the experimental value and could be interpreted as the effect of partly bosonic neutrino with sin 2 χ ∼ 0.4.…”

We assume that the Pauli exclusion principle is violated for neutrinos, and thus, neutrinos obey at least partly the Bose-Einstein statistics. The parameter sin 2 χ is introduced that characterizes the bosonic (symmetric) fraction of the neutrino wave function. Consequences of the violation of the exclusion principle for the twoneutrino double beta decays (2νββ-decays) are considered. This violation strongly changes the rates of the decays and modifies the energy and angular distributions of the emitted electrons. Pure bosonic neutrinos are excluded by the present data. In the case of partly bosonic (or mixed-statistics) neutrinos the analysis of the existing data allows to put the conservative upper bound sin 2 χ < 0.6. The sensitivity of future measurements of the 2νββ-decay to sin 2 χ is evaluated.

“…The SSD hypothesis has been studied both experimentally [6,[10][11][12] and theoretically [7][8][9]. The required beta transition amplitudes to the 1 + 1 state have been deduced from the measured logf t values, i.e., in the model independent way, or have been calculated e.g.…”

The hypothesis of the single state dominance (SSD) in the calculation of the two-neutrino double beta decay (2νββ-decay) of 100 M o is tested by exact consideration of the energy denominators of the perturbation theory. Both transitions to the ground state as well as to the 0 + and 2 + excited states of the final nucleus 100 Ru are considered. We demonstrate, that by experimental investigation of the single electron energy distribution and the angular correlation of the outgoing electrons, the SSD hypothesis can be confirmed or ruled out by a precise 2νββ-decay measurement (e.g. by NEMO III collaboration). 21.60.Jz; 23.40.Bw; 23.40.Hc PACS number(s):

“…In cases where the ground state of the intermediate nucleus has a spin and parity of J π = 1 + , its electron capture (EC) and β-decay rates to the J π = 0 + parent and daughter, respectively, are both experimentally accessible, potentially providing direct benchmarks [4][5][6]. In the cases of 100 Mo and 116 Cd, for which the intermediate ground states have J π = 1 + , the 2νββ decay matrix elements estimated using only the groundstate virtual transitions roughly reproduce the measured 2νββ decay rates [7][8][9][10], qualitatively consistent with the single-state dominance (SSD) hypothesis [11][12][13][14] 116 Cd reaction at 450 MeV and reported a value of B(GT) = 0.032 ± 0.005 [17] that was later revised to be 0.14 ± 0.03 due to problems with the target [18]. A recent (p, n) measurement at 300 MeV by Sasano et al yielded B(GT) = 0.28 ± 0.03 [8,19].…”
