Weak-interaction and nuclear-structure aspects of nuclear double beta decay

J Suhonen, O Civitarese - Physics Reports, 1998 - Elsevier
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 …

Local density approximation for proton-neutron pairing correlations: Formalism

E Perlińska, SG Rohoziński, J Dobaczewski… - Physical Review C …, 2004 - APS
In the present study we generalize the self-consistent Hartree-Fock-Bogoliubov (HFB) theory
formulated in the coordinate space to the case which incorporates an arbitrary mixing …

Proton-neutron pairing in nuclei with

AL Goodman - Physical Review C, 1999 - APS
The ground states of even-even Z= N nuclei are determined with the isospin generalized
BCS equations and the HFB equation. The calculations permit the simultaneous existence of …

Proton-neutron pairing in the deformed BCS approach

F Šimkovic, CC Moustakidis, L Pacearescu… - Physical Review C …, 2003 - APS
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 …

Thermodynamics of a Condensate in Asymmetric Nuclear Matter

A Sedrakian, U Lombardo - Physical Review Letters, 2000 - APS
We study the neutron-proton pairing in nuclear matter as a function of isospin asymmetry at
finite temperatures and the empirical saturation density using realistic nuclear forces and …

Neutron-proton pairing in the BCS approach

O Civitarese, M Reboiro, P Vogel - Physical Review C, 1997 - APS
We investigate the BCS treatment of neutron-proton pairing involving time-reversed orbits.
We conclude that an isospin-symmetric Hamiltonian, treated with the help of the generalized …

Unravelling the band crossings in and The quest for pairing

SM Fischer, CJ Lister, DP Balamuth - Physical Review C, 2003 - APS
High-spin band crossings in N= Z nuclei have been suggested to contain information on T=
0 neutron-proton pairing correlations. Several experiments that produced high angular …

Many-body correlations of quasiparticle random-phase approximation in nuclear matrix elements of neutrinoless decay

J Terasaki - Physical review C, 2015 - APS
We show that the correlations of the quasiparticle random-phase approximation (QRPA)
significantly reduce the nuclear matrix element (NME) of neutrinoless double-β decay by a …

Y He, X Yu, HF Zhang - Chinese Physics C, 2021 - cpc.ihep.ac.cn
In this contribution, the preformation factors of 606 nuclei are extracted within the framework
of the generalized liquid drop model (GLDM). Through the systematic analysis of the …

Phases of asymmetric nuclear matter with broken space symmetries

H Müther, A Sedrakian - Physical Review C, 2003 - APS
Isoscalar Cooper pairing in isospin asymmetric nuclear matter occurs between states
populating two distinct Fermi surfaces, each for neutrons and protons. The transition from a …
