“…(25) The allowed region for m ββ is presented by the region between two parallel lines in the upper part of Fig.1. It is evident that the Majorana mass mechanism of the 0νββ-decay can be checked also in the case of the quasi-degenerate spectrum if m 0 is known (from cosmological observations or from future β-decay experiments KATRIN [52,53] and MARE [54]).…”

From the standard seesaw mechanism of neutrino mass generation, which is based on the assumption that the lepton number is violated at a large (∼ 10 15 GeV) scale, follows that the neutrinoless double-beta decay (0νββ-decay) is ruled by the Majorana neutrino mass mechanism. Within this notion, for the inverted neutrino-mass hierarchy we derive allowed ranges of half-lives of the 0νββ-decay for nuclei of experimental interest with different sets of nuclear matrix elements. The present-day results of the calculation of the 0νββ-decay nuclear matrix elements are briefly discussed. We argue that if 0νββ-decay will be observed in future experiments sensitive to the effective Majorana mass in the inverted mass hierarchy region, a comparison of the derived ranges with measured half-lives will allow us to probe the standard seesaw mechanism assuming that future cosmological data will establish the sum of neutrino masses to be about 0.2 eV.

“…Laboratory measurements of the beta spectrum of tritium [4,5] yield an upper limit on the absolute scale of neutrino mass of less than 2 eV. Given that the mass must then lie in this range, new, sensitive laboratory measurements are being pursued [6][7][8] to shed further light on the mechanism for neutrino mass generation.…”

Background: The standard kinematic method for determining neutrino mass from the beta decay of tritium or other isotope is to measure the shape of the electron spectrum near the endpoint. A similar distortion of the "visible energy" remaining after electron capture is caused by neutrino mass. There has been a resurgence of interest in using this method with 163 Ho, driven by technological advances in microcalorimetry. Recent theoretical analyses offer reassurance that there are no significant theoretical uncertainties.Purpose: The theoretical analyses consider only single vacancy states in the daughter 163 Dy atom. It is necessary to consider configurations with more than one vacancy that can be populated owing to the change in nuclear charge. Method:The shakeup and shakeoff theory of Carlson and Nestor is used as a basis for estimating the population of double-vacancy states.Results: A spectrum of satellites associated with each primary vacancy created by electron capture is presented. Conclusions:The theory of the calorimetric spectrum is more complicated than has been described heretofore. There are numerous shakeup and shakeoff satellites present across the spectrum, and some may be very near the endpoint. The spectrum shape is presently not well enough understood to permit a sensitive determination of the neutrino mass in this way.

“…MARE I might reach a statistical sensitivity of 4 eV after 3 years of data taking [3]. MARE II is to challenge the KATRIN goal of 0.2 eV [3]. The aim of this paper is to derive the form of the endpoint spectrum of emitted electrons for the β-decay of 187 Re, which is needed to extract the effective neutrino mass m β or to place a limit on this quantity from future MARE I and II experiments.…”

The planned rhenium β-decay experiment, called the "Microcalorimeter Arrays for a Rhenium Experiment" (MARE), might probe the absolute mass scale of neutrinos with the same sensitivity as the Karlsruhe tritium neutrino mass (KATRIN) experiment, which will take commissioning data in 2011 and will proceed for 5 years. We present the energy distribution of emitted electrons for the first unique forbidden β-decay of 187 Re. It is found that the p-wave emission of electron dominates over the s-wave. By assuming mixing of three neutrinos the Kurie function for the rhenium β-decay is derived. It is shown that the Kurie plot near the endpoint is within a good accuracy linear in the limit of massless neutrinos like the Kurie plot of the superallowed β-decay of 3 H.
