A Semi-Empirical Formula for Two-Neutrino Double-Beta Decay
Ovidiu Niţescu, Fedor Šimkovic
We propose a semi-empirical formula (SEF) for calculating the nuclear matrix elements (NMEs) for two-neutrino double-beta decay. The SEF's dependence on the proton and neutron numb…

Radiative and exchange corrections for two-neutrino double-beta decay
Ovidiu Niţescu, Fedor Šimkovic
We investigate the impact of radiative and atomic exchange corrections in the two-neutrino double-beta ()-decay of Mo. In the calculation of the exchange correctio…

High-precision measurements of the atomic mass and electron-capture decay value of Tc
Zhuang Ge, Tommi Eronen, Vasile Alin Sevestrean +25
A direct measurement of the ground-state-to-ground-state electron-capture decay value of Tc has been performed utilizing the double Penning trap mass spectrometer JYFLTR…
