“…Another promising candidate is 136 Xe [8] where high sensitivity should be achievable by making use of several tons of isotopically enriched, high-purity liquid or gaseous 136 Xe in a time projection chamber [9]. Here, energy resolution [3,10] is lower than for Ge detectors, but background suppression is improved by spatial tracking of the electrons and, ultimately, could be greatly improved by laser-induced-fluorescence single-ion detection of 136 Ba daughter ions [11][12][13].…”

The atomic mass of 136Xe has been measured by comparing cyclotron frequencies of single ions in a Penning trap. The result, with 1 standard deviation uncertainty, is M(136Xe)=135.907 214 484 (11) u. Combined with previous results for the mass of 136Ba [Audi, Wapstra, and Thibault, Nucl. Phys. A 729, 337 (2003)10.1016/j.nuclphysa.2003.11.003], this gives a Q value (M[136Xe]-M[136Ba])c(2)=2457.83(37) keV, sufficiently precise for ongoing searches for the neutrinoless double-beta decay of 136Xe.

“…Identification of the two electrons provides a powerful disciminant against backgrounds from γ, α and β emitters in the apparatus. The use of 136 Xe [109,110] as a fill gas in a tracking type system gives high efficiency for a large number of emitters (4 × 10 25 in the case of the largest experiment) by using the source as the detection medium. Other experiments [111,112,117,118,119,120,115] suspend the 0νββ emitter in the tracking volume.…”

The question of neutrino mass is one of the major riddles in particle physics. Recently, strong evidence that neutrinos have nonzero masses has been found. While tiny, these masses could be large enough to contribute significantly to the mass density of the universe. The evidence for nonvanishing neutrino masses is based on the apparent observation of neutrino oscillation-the transformation of a neutrino of one type or "flavor" into one of another. We explain the physics of neutrino oscillation, and review and weigh the evidence that it actually occurs in nature. We also discuss the constraints on neutrino mass from cosmology and from experiments with negative results. After presenting illustrative neutrino mass spectra suggested by the present data, we consider how near-and far-future experiments can further illuminate the nature of neutrinos and their masses.

“…The two-neutrino mode for 136 Xe has not yet been observed, and the existing limits on the half-life period vary widely, from T 1/2 > 10 20 yr to T 1/2 > 10 22 yr [9][10][11][12][13].…”
