A Nuclear Structure Model for Double Charge-Exchange Processes
V. dos S. Ferreira, A. R. Samana, F. Krmpotić +1
A new model, based on the BCS approach, is specially designed to describe nuclear phenomena of double-charge exchange (DCE). After being proposed, and…
Muon capture rates within the projected QRPA
Danilo Sande Santos, Arturo R. Samana, Francisco Krmpotić +1
The conservation of the number of particles within the QRPA plays an important role in the evaluation muon capture rates in all light nuclei with A \precsim 30 . The violation of t…
Double Beta Decay within the Relativistic QRPA
Cláudio De Conti, Francisco Krmpotić, Brett Vern Carlson
We perform a self-consistent relativistic QRPA (RQRPA) calculation of $2ν\b\b$-decay based on relativistic BCS (RBCS) mean field theory results for odd-odd intermediate nuclei $^{4…
Neutrino and antineutrino charge-exchange reactions on 12C
A. R. Samana, F. Krmpotic, 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…
QRAP: a numerical code for projected (Q)uasi-particle (RA)ndom (P)hase approximation
F. Krmpotic, A. R. Samana, C. A. Bertulani
A computer code for quasiparticle random phase approximation-QRPA and projected quasiparticle random phase approximation-PQRPA models of nuclear structure is explained in details.…
Gross Theory Model for Neutrino-Nucleus Cross Section
A. R. Samana, C. A. Barbero, S. B. Duarte +2
The nuclear gross theory, originally formulated by Takahashi and Yamada for the -decays, is applied for the electronic-neutrino nucleus reactions, employing a more realistic des…
