Abstract In this review we will present the results of recent $$\beta $$ ? -decay studies using total absorption technique that cover topics interest for applications, nuclear structure and astrophysics. The decays studied were selected primarily because they have a large impact on prediction (a) decay heat i...

Results of observations of low energy nuclear and electron recoil events in liquid xenon scintillator detectors are given. The relative scintillation efficiency for nuclear recoils is 0.22 ± 0.01 in the recoil energy range 40 keV 70 keV. Under the assumption of a single dominant decay component to the scintillation pulse-shape the log-normal mean parameter T0 of the maximum likelihood estimator...

(ββ) 0 ν-decay, the problem of the nuclear matrix elements Abstract The existing calculations of the nuclear matrix elements of the neu-trinoless double β-decay differ by about a factor three. This uncertainty prevents quantative interpretation of the results of experiments searching for this process. We suggest here that the observation of the neutrinoless double β-decay of several nuclei in t...

(ββ) 0 ν-decay: a possible test of the nuclear matrix element calculations Abstract The existing calculations of the nuclear matrix elements of the neutrinoless double β-decay differ by about a factor three. This uncertainty prevents quantitative interpretation of the results of experiments searching for this process. We suggest here that the observation of the neutrinoless double β-decay of se...
