-decay half-lives of even-even nuclei using the recently introduced phase space recipe
Jameel-Un Nabi, Mavra Ishfaq, Ovidiu Nitescu +2
We present the beta decay half-lives calculation for selected even even nuclei that decay through electron emission. The kinematical portion of the half-life calculation was perfor…
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…
Atomic corrections for the unique first forbidden transition of Re
O. Niţescu, R. Dvornický, F. Šimkovic
In this paper, we reexamine one of the most promising candidates for determining the neutrino mass scale -- the unique first forbidden transition from Re() to $^…
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…
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…
Study of the effect of newly calculated phase space factor on beta-decay half-lives
Jameel-Un Nabi, Mavra Ishfaq, Ovidiu Nitescu +2
We present results for -decay half-lives based on a new recipe for calculation of phase space factors recently introduced. Our study includes -shell and heavier nuclei of ex…
New phase space calculations for beta-decay half-lives
Sabin Stoica, Mihail Mirea, Ovidiu Nitescu +2
We revisit the computation of the phase space factors (PSF) involved in the positron decay and electron capture (EC) processes for a large number of nuclei of experimental interest…
