Double β decays of100Moand150Nd

The single state dominance hypothesis and the two-neutrino double beta decay of100Mo

“…1b) states of the final nucleus were normalized to the experimental half-lifes of Ref. [15] and Ref. [13] (see Table II), respectively.…”

Two-neutrino double- β decay of 94 ⩽ A ⩽ 110 nuclei for the 0+ → 0+ transition

“…The predicted T 2ν 1/2 in QRPA by Staudt et al [45] and in OEM by Hirsch et al [46] are larger than our predicted value for g A =1.0 by approximately a factor of 2 and 4 respectively. The 2ν ββ decay of 100 Mo for 0 + →0 + transition have been investigated by many experimental groups [18,51,[57][58][59][60][61][62][63][64][65] as well as theoreticians by employing different theoretical frameworks [29,30,[45][46][47]52,53,56,[66][67][68]. In comparison to the experimental M 2ν , the theoretically calculated value given by Stoica using SRPA(WS) [53] is too small.…”

YAG:Nd crystals as possible detector to search for and decay of neodymium

“…Two neutrino 2β decay of 150 Nd with the half-life T 1/2 = 1.9 +0.7 −0.4 × 10 19 yr was observed in experiment [17] by using a time projection chamber and samples of enriched 150 Nd and natural neodymium. In [18] the double beta decay of 150 Nd was studied with similar technique (only enriched 150 Nd sample was used). The two-neutrino half-life T 1/2 = (6.8 ± 0.8) × 10 18 yr was measured.…”

“…[20]. The most stringent limit on the neutrinoless mode T 1/2 ≥ 1.2 × 10 21 yr was set in the experiment [18].…”
