The QRPA and beyond
(1998)
2ν double beta decay within the relativistic QRPA
(2011-01-01)
We perform a self-consistent relativistic QRPA (RQRPA) calculation of 2νββ-decay based on relativistic BCS (RBCS) mean field theory results for odd-odd intermediate nuclei 48Sc, 76As, 82Br, 100Tc, 128I, and 130I. The RBCS ...
Computer code for double beta decay QRPA based calculations
(Amer Inst Physics, 2014-01-01)
The computer code developed by our group some years ago for the evaluation of nuclear matrix elements, within the QRPA and PQRPA nuclear structure models, involved in neutrino-nucleus reactions, muon capture and beta(+/-) ...
Prospective study on microscopic potential with Gogny interaction
(Springer, 2015)
We present our current studies and future plans on microscopic potential based on effective nucleon-nucleon interaction and many-body theory. This framework treats in an unified way nuclear structure and reaction. It offers ...
Double-beta-decay nuclear matrix elements in the QRPA framework
(IOP Publishing, 2012-08)
We review the recent work done by the Jyväskylä-La Plata collaboration on the calculation of nuclear matrix elements for various modes of double-beta decays. Whenever helpful, we connect our recent work to the historical ...
Double-beta decay in pn-QRPA model with isospin and SU(4) symmetry constraints
(1994-05-23)
The transition matrix elements for the 0+ → 0+ double-beta decays are calculated for 48Ca, 76Ge, 82Se, 100Mo, 128Te and 130Te nuclei, using a δ-interaction. As a guide, to fix the particle-particle interaction strengths, ...
