Direct Calculation of the Two-Neutrino Double-Beta Decay Rate Including the Full Lepton-Energy Dependence
S. A. Ghinescu, Stefan-Alexandru Ghinescu, Andrei Neacsu +3
The calculation of the two-neutrino double-beta decay (DBD) rates has so far relied on approximations that decouple the nuclear structure from the emitted lepton kinematics. To ens…
Updated Results for Kinematic Factors in Double Beta Decays
S. Ghinescu, S. Stoica
Accurate calculations of phase space factors (PSFs), electron energy spectra and angular correlations are essential for designing and interpreting double-beta decay (DBD) experimen…
Theoretical analysis and predictions for the double electron capture of Xe
Ovidiu Niţescu, Stefan Ghinescu, Vasile-Alin Sevestrean +3
We provide a complete theoretical description of the two-neutrino electron capture in Xe, improving both the nuclear and the atomic structure calculations. We improve the g…
Self-consistent calculations for atomic electron capture
V. A. Sevestrean, O. Niţescu, S. Ghinescu +1
We present a comprehensive investigation of electron capture (EC) ratios spanning a broad range of atomic numbers. The study employs a self-consistent computational method that inc…
Semi-microscopic theory of two proton emission
S. A. Ghinescu, D. S. Delion
We propose a semi-microscopic model for the simultaneous emission of two protons. This model has the advantage of avoiding certain technical aspects of a fully microscopic 3-body f…
Investigation of the Lorentz invariance violation in two-neutrino double-beta decay
S. A. Ghinescu, O. Nitescu, S. Stoica
We make a comprehensive investigation of the Lorentz invariance violation (LIV) effects that may occur in two-neutrino double-beta () decay for all the experimentally interes…
Probing Lorentz violation in using single electron spectra and angular correlations
O. V. Nitescu, S. A. Ghinescu, M. Mirea +1
We show that the current search for Lorentz invariance violation (LIV) in the summed energy spectra of electrons in decay can be extended by investigating the single electro…
Lorentz violation effects in two neutrino double-beta decay
Ovidiu Nitescu, Stefan Ghinescu, Sabin Stoica
Observable effects for the Lorentz invariance violation (LIV) at a low energy scale can also be investigated in double beta decay (DBD). For example, by comparing the theoretical p…
