Tables of double beta decay data

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

“…The great interest to the double beta (2β) decay search is related, in particular, with the recent evidence of neutrino oscillations which strongly suggests that neutrinos have nonzero mass [1,2,3,4]. While oscillation experiments are sensitive to the neutrinos mass difference, only the measured neutrinoless (0ν) double beta decay rate could set the Majorana nature of the neutrinos and give the absolute scale of the effective neutrino mass.…”

Double beta decay—Physics beyond the standard model now, and in future (GENIUS)

“…No one of them will pass below ∼ 0.1 − 0.2 eV (see section 4.1) A detailed discussion of the various experimental possibilities can be found in [Kla95,Kla96,Kla96a]. A useful listing of existing data from the various ββ emitters is given in [Tre95].…”

High sensitivity GEM experiment on 2β decay of76Ge

“…Despite the numerous efforts to detect 0ν2β decay, this process still remains unobserved [3,4]. The highest half-life limits were set in direct experiments with several nuclides: T 76 Ge [19,20].…”

“…The width of this peak is determined by the detector energy resolution. The sensitivity of the set up for 2β decay study can be expressed in terms of a lower half-life limit as following [3,4]:…”
