General behavior of double beta decay amplitudes in the quasiparticle random phase approximation.
Simple formulae for the 0+ → 0+ double beta decay matrix elements, as a function of the particle-particle strength gpp, have been designed within the quasiparticle random phase approximation. The 2ν amplitude is a bilinear function of gpp, and all 0ν moments behave as ratios of a linear function and the square root of another linear function of gpp. It is suggested that these results are of gen...
متن کاملNon-collapsing quasiparticle random phase approximation for nuclear double-beta decay
We show how the longstanding problem of the collapse of the charge-exchange QRPA near the physical value of the force strength can be circumvented. This is done by including the effect of ground state correlations into the QRPA equations of motion. The corresponding formalism, called renormalized QRPA, is briefly outlined and its consequences are discussed in the framework of a schematic model ...

متن کاملNeutrinoless double beta decay within Self-consistent Renormalized Quasiparticle Random Phase Approximation and inclusion of induced nucleon currents
The first, to our knowledge, calculation of neutrinoless double beta decay (0νββ-decay ) matrix elements within the self-consistent renormalized Quasiparticle Random Phase Approximation (SRQRPA) is presented. The contribution from the momentum-dependent induced nucleon currents to 0νββdecay amplitude is taken into account. A detailed nuclear structure study includes the discussion of the sensit...
متن کاملDeformed quasiparticle random phase approximation formalism for single- and two-neutrino double b decay
We use a deformed quasiparticle random phase approximation formalism to describe simultaneously the energy distributions of the single b Gamow-Teller strength and the two-neutrino double b decay matrix elements. Calculations are performed in a series of double b decay partners with A=48, 76, 82, 96, 100, 116, 128, 130, 136, and 150, using deformed Woods-Saxon potentials and deformed Skyrme Hart...
