The possibility of observing neutrinoless double {beta} decay offers the opportunity of determining the effective neutrino mass if the nuclear matrix element were known. Theoretical calculations are uncertain, and the occupation of valence orbits by nucleons active in the decay is likely to be important. The occupation of valence proton orbits in the ground states of {sup 76}Ge, a candidate for such decay, and {sup 76}Se, the corresponding daughter nucleus, is determined by precisely measuring… Expand

Status and prospects of searches for neutrinoless double beta decay
The simultaneous beta decay of two neutrons in a nucleus without the emission of neutrinos (called neutrinoless double beta decay) is a lepton number violating process which is not allowed in theExpand
Effects of orbital occupancies and spin–orbit partners on 0νββ-decay rates
Abstract Neutrinoless double beta ( 0 ν β β ) decay of the 76Ge, 82Se, 128Te, 130Te and 136Xe nuclei is discussed in terms of the associated nuclear matrix element (NME). The effects of the size ofExpand
Neutrino-nucleus reactions and their role for supernova dynamics and nucleosynthesis
The description of nuclear reactions induced by supernova neutrinos has witnessed significant progress during the recent years. At the energies and momentum transfers relevant for supernova neutrinosExpand
We review the particle physics aspects of neutrino-less double beta decay. This process can be mediated by light massive Majorana neutrinos (standard interpretation) or by something elseExpand
Constraints on Light Neutrino Parameters Derived from the Study of Neutrinoless Double Beta Decay
The study of the neutrinoless double beta decay mode can provide us with important information on the neutrino properties, particularly on the electron neutrino absolute mass. In this work we reviseExpand
Sense and sensitivity of double beta decay experiments
The search for neutrinoless double beta decay is a very active field in which the number of proposals for next-generation experiments has proliferated. In this paper we attempt to address both theExpand
Searches for neutrinoless double beta decay
Neutrinoless double beta decay is a lepton number violating process whose observation would also establish that neutrinos are their own anti-particles. There are many experimental efforts with aExpand
Double beta decay: A problem of particle, nuclear and atomic physics
A brief review of recent progress in the field of double beta decay is presented. Different aspects from particle, nuclear and atomic physics of both two-neutrino (2νββ2νββ) and neutrinolessExpand
Single and double beta decays in the , and triplets of isobars
Abstract In this paper we analyze the ground-state-to-ground-state two-neutrino double beta ( 2 ν β β ) decays and single EC and β − decays for the A = 100 ( 100 Mo– 100 Tc– 100 Ru), A = 116 ( 116Expand
