Neutrinoless double-beta decay, which is a very old and yet elusive process, is reviewed. Its
observation will signal that the lepton number is not conserved and that the neutrinos are …

Neutrino–nuclear responses associated with astro-neutrinos, single beta decays and double
beta decays are crucial in studies of neutrino properties of interest for astro-particle physics …

The observation of neutrinoless double beta decay (DBD) will have important
consequences. First it will signal that lepton number is not conserved and the neutrinos are …

Double-beta processes play a key role in the exploration of neutrino and weak interaction
properties, and in the searches for effects beyond the standard model. During the last half …

In this article a comprehensive description and performance of the double Penning-trap
setup JYFLTRAP will be detailed. The setup is designed for atomic mass measurements of …

The Q values of the 116Cd and 130Te double-beta decaying nuclei were determined by
using a Penning trap mass spectrometer. The new atomic mass difference between 116Cd …

The process of neutrinoless double electron (0 ν ECEC) capture is revisited for those cases
where the two participating atoms are nearly degenerate in mass. The theoretical framework …

A complete and improved calculation of phase space factors (PSF) for 2 ν β+ β+ and 0 ν β+
β+ decay, as well as for the competing modes 2 ν EC β+, 0 ν EC β+, and 2 ν ECEC, is …

In the search for the nuclide with the largest probability for neutrinoless double-electron
capture, we have determined the Q ϵ ϵ value between the ground states of Gd 152 and Sm …

A new generation of neutrinoless double-beta decay (0νββ-decay) experiments with
improved sensitivity is currently being designed and under construction. They will probe the …
