Resonant enhancement of neutrinoless double-electron capture in 152Gd
In the search for the nuclide with the largest probability for neutrinoless double-electron capture, we have determined the Qϵϵ value between the ground states of 152Gd and 152Sm by Penning-trap mass-ratio measurements. The new Qϵϵ value of 55.70(18) keV results in a half-life of 1026 yr for a 1 eV...

| Zusammenfassung: | In the search for the nuclide with the largest probability for neutrinoless double-electron capture, we have determined the Qϵϵ value between the ground states of 152Gd and 152Sm by Penning-trap mass-ratio measurements. The new Qϵϵ value of 55.70(18) keV results in a half-life of 1026 yr for a 1 eV neutrino mass. With this smallest half-life among known 0νϵϵ transitions, 152Gd is a promising candidate for the search for neutrinoless double-electron capture. |
