“…As expected from the materials screening campaign, we find in the data that the primary backgrounds to 2νββ in EXO-200 are gamma and beta interactions due to trace quantities of 40 K, 232 Th, and 238 U in the detector materials. We separate these backgrounds from 2νββ candidates by taking advantage of the detector's good energy and position resolution and its ability to perform pattern recognition.…”

We report on an improved measurement of the 2νββ half-life of 136 Xe performed by EXO-200. The use of a large and homogeneous time projection chamber allows for the precise estimate of the fiducial mass used for the measurement, resulting in a small systematic uncertainty. We also discuss in detail the data analysis methods used for double-beta decay searches with EXO-200, while emphasizing those directly related to the present measurement. The 136 Xe 2νββ half-life is found to be T 2νββ 1/2 = 2.165 ± 0.016(stat) ± 0.059(sys) · 10 21 years. This is the most precisely measured half-life of any 2νββ decay to date.

“…In all cases the experiment has made the most precise measurement of the 2νββ half-life [2,[30][31][32]. The 48 Ca source in NEMO-3 consists of nine disks of CaF 2 powder contained in thin (≈10 μm) Teflon and polyethylene envelopes.…”

Limits are also set on models involving Majoron emission and right-handed currents.

“…For all seven isotopes, a search for two-neutrino decay, neutrinoless decay and decays with the Majoron emission has been performed. As a result, half-life values of 2νββ decay have been measured for all seven isotopes [61,60,70,62,66,67,127]. In addition 2νββ decay of 100 Mo to the 0 + 1 excited state of 100 Ru has been detected too [128].…”

“…Limits on neutrinoless double beta decay and on decays with the Majoron emission for all seven isotopes have also been established [61,60,70,62,66,67,69,127]. In particular, for 100 Mo, the limit T 1/2 (0ν) > 1.1 × 10 24 yr ( m ν < 0.33 − 0.62 eV) has been achieved [62].…”
