Description of the 2νββ decay within a fully renormalised RPA approach

Erratum: Two-neutrino double β decay within fully renormalized quasiparticle random-phase approximation: Effect of the restoration of the Ikeda sum rule [Phys. Rev. C68, 064310 (2003)]

“…That means that there are no spurious low-lying solutions in the present theoretical scheme which would be generated by the scattering terms considered as independent constituents of the phonon operator (as proposed in [17]). …”

“…The proton and neutron pairing gaps are determined phenomenologically to reproduce the odd-even mass differences through a symmetric fiveterm formula [18]. Then the equations for the chemical potentials (17) are solved for proton and neutron subsystems. The pairing gaps entering the BCS equations are given in the Table I.…”

“…Interesting properties for these equations and their solutions are discussed in our previous publications [11,12]. Here we mention one of these features.…”

“…[11], we showed that all these operators can be renormalized as suggested by the commutation equations:…”

“…Labeling the states according to their energies ordering, the single particle space is defined by the indices interval [11,62]. The dimensions for the spaces (S + , S − ) are (163, 1) and (158, 5) for the mother and daughter nuclei, respectively.…”
