We review the status and prospects of heavy-ion double charge exchange (HI-DCE)
reactions. Their important role for nuclear reaction, nuclear structure and double beta-decay …

Shape coexistence in nuclei appears to be unique in the realm of finite many-body quantum
systems. It differs from the various geometrical arrangements that sometimes occur in a …

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 …

Background: Direct determination of the neutrino mass through double-β decay is at the
present time one of the most important areas of experimental and theoretical research in …

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 …

A self-consistent calculation of nuclear matrix elements of the neutrinoless double-beta
decays (0 ν β β) of Ge 76, Se 82, Zr 96, Mo 100, Cd 116, Te 128, Te 130, and Xe 136 is …

We review recent developments in double-beta decay, focusing on what can be learned
about the three light neutrinos in future experiments. We examine the effects of uncertainties …

This paper introduces the neutrinoless double‐beta decay (the rarest nuclear weak process)
and describes the status of the research for this transition, both from the point of view of …

We present a precision analysis of the Xe 136 two-neutrino β β electron spectrum above 0.8
MeV, based on high-statistics data obtained with the KamLAND-Zen experiment. An …

Single-nucleon transfer reactions are processes that selectively probe single-particle
components of the populated many-body nuclear states. In this context, recent efforts have …
