Neutrinoless -Decay in DCEQTDA

C. De Conti, V. dos S. Ferreira, A. R. Samana +2

We have recently developed a nuclear model, which is a natural extension of the -QRPA model, specially designed to describe double charge exchange (DCE) processes generated by…

Neutrino and antineutrino cross sections in C

A. R. Samana, F. Krmpotić, N. Paar +1

We extend the formalism of weak interaction processes, obtaining new expressions for the transition rates, which greatly facilitate numerical calculations, both for neutrino-nucleu…

RPA puzzle in C(12) weak decay processes

F. Krmpotic, A. Mariano, A. Samana

We explain the origin of the difficulties that appear in a straightforward application of the QRPA in C(12), and we demonstrate that it is imperative to use the projected QRPA (PQR…

Self Consistent and Renormalized particle-particle RPA in a Schematic Model

E. J. V. de Passos, A. F. R. de Toledo Piza, F. Krmpotić

The dynamical effects of ground state correlations for excitation energies and transition strengths near the superfluid phase transition are studied in the soluble two level pairin…

On the energy-shell contributions of the three-particle~-~ three-hole excitations

A. Mariano, F. Krmpotić, A. F. R. de Toledo Piza

The response functions for the extended second and third random phase approximation are compared. A second order perturbation calculation shows that the first-order amplitude for t…
