Weak-interaction and nuclear-structure aspects of double beta decay are reviewed. Starting
from effective electroweak lagrangians, decay rates for the two-neutrino and neutrinoless …

We review the recent developments in the field of nuclear double beta decay, which is
presently an important topic in both nuclear and particle physics. The mechanism of lepton …

We use the axially deformed Skyrme quasiparticle random-phase approximation (QRPA)
together with the SkM* energy-density functional, both as originally presented and with the …

We have investigated the role of proton-neutron pairing in the context of the quasiparticle
random phase approximation formalism. This way the neutrinoless double beta decay matrix …

The self-consistent finite Fermi-system theory with three different parameter sets is used to
calculate decay energies and Gamow-Teller strength distributions of neutronrich short-lived …

The effect of deformation on the two-neutrino double decay (2νββ-decay) for ground state
transition 76Ge→ 76Se is studied in the framework of the deformed QRPA with separable …

We examine the violation of the Pauli exclusion principle in the Quasiparticle Random
Phase Approximation (QRPA) calculation of the two-neutrino double beta decay matrix …

We examine isovector and isoscalar proton-neutron-pairing correlations for the ground state
of even-even Ge isotopes with mass number A= 64–76 within the deformed BCS approach …

It has recently been proposed that 41 92 Nb and 43 98 Tc may have been formed in the ν-
process. We investigate the neutrino induced reactions related to the ν-process origin of …

The sum of the Gamow-Teller (GT) strength in 1p0f shell nuclei is investigated by the
Quasiparticle Random Phase Approximation (QRPA), where BCS and RPA ground-state …
