This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Using 9.4 g of Zr-96 and 1221 days of data from the NEMO-3 detector corresponding to 0.031 kgy, the obtained 2vbb decay half-life measurement is [2.35 \pm 0.14(stat) \pm 0.16(syst)] \times 10_{19}yr. Different characteristics of the final state electrons have been studied, such as the energy sum, individual electron energy, and angular distribution. The 2v nuclear matrix element is extracted using the measured 2vbb half-life and is 0.049 \pm 0.002. The 0vbb decay half-life is excluded at the 90% CL to > 9.2 \times 10_ {21}yr corresponding to a limit on the effective Majorana neutrino mass of

This book was released on 2014 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the NEMO-3 detector, 410.4 g of 116Cd with a total exposure of 1.65 kg· y and 932 g of 82Se with a total exposure of 3.75 kg· y were used to measure the half-life of two-neutrino double beta decay (2[nu][beta][beta]) to the ground states of 116Sn and 82Kr and to place a lower limit on the neutrinoless double becay decay (0[nu][beta][beta]) to the same ground states. Under the single-states dominance hypothesis, the 2[nu][beta][beta] half-lives are found to be T 1/2(116Cd) = (2.90 ± 0.03(stat) ± 0.15(syst)×1019 yr and T 1/2(82Se) = [10.62±0.11(stat)±0.56(syst)]×1019 yr. 0[nu][beta][beta] is excluded to 90% confidence level at T 1/2 ≥ 1.12 × 1023 yr for 116Cd and T 1/2 ≥ 3.90 × 1023 yr for 82Se. These half-lives correspond to effective Majorana neutrino masses of m ≤ (4.33 - 5.54) eV and m ≤ (2.28 - 2.82) eV, respectively, in the light Majorana exchange mechanism.

Basharina-Freshville and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's most precise half-life measurement of T 2nu_1/2 = [7.02 ± 0.01(stat) ± 0.46(syst)] × 10 18 years has been made for the 2\nu\beta\beta decay of 100Mo using data from 6.9kg collected with the NEMO3 detector over 1471 days. The 2\nu nuclear matrix element has been extracted using T 2nu_1/2 and is M 2\nu = 0.126 ± 0.004. The 0\nu\beta\beta search yielded a limit on the half-life of T 0\nu_1/2 1/1 > 1.1 × 10 24 years at the 90% CL, corresponding to a limit on the effective Majorona mass of \langle M\nu e\rangle

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents searches for several modes of double beta decays of 136Xe to two low-lying excited levels of 136Ba. For each final level, both 2[nu] and 0[nu] double beta decay processes are considered. The data and general techniques developed by the EXO-200 collaboration are used, including a Machine Learning process to improve sensitivity in multivariate space. EXO-200 is an experimental program searching for 0[nu][beta][beta] decay in a time projection chamber filled with 175 kg of liquid Xenon enriched to 80% 136Xe, functioning as both source and detector. Experimental searches of double beta decay with 136Xe and other isotopes are motivated by non Standard Model neutrinoless decay (0[nu][beta][beta]) possibilities. If found this would imply the Majorana nature of neutrinos, provide access to the currently unknown absolute mass scale of the neutrino, and violate lepton conservation by 2 units. Nuclear matrix elements necessary to connecting observed neutrinoless halflife to the neutrino mass scale depend on nuclear models. Observation of both the 2[nu] 0+ excited and 0+ ground state in a single element may constrain these models. Sensitivity studies of search performance are described, and final sensitivities from 7.86 · 10^23 years to 2.00 · 10^25 years are reported.
