Description

We present the normalized distributions of released energy in the EC decay, a tool to obtain the neutrino mass. Our calculations include the exchange and overlap corrections, the shake-up and shake-off atomic effects, the electron screening effects and the intrinsic line widths of Breit–Wigner resonances.
In computing the electrons' wave functions, we used the Dirac-Hartree-Fock-Slater self-consistent method, which was validated in a previous study for such calculations.
We consider two allowed transitions of $^{95}$Tc to $^{95}$Mo for our calculations using the first direct measurement of the gs-to-gs EC Q value of $^{95}$Tc with the JYFLTRAP penning trap mass spectrometry.
