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…
