AbstraktAbstract
We study a new mode of the neutrinoless and two-neutrino double-beta decays in which a single electron is emitted from the atom. The other electron is directly produced in one of the empty s_1/2 or p_1/2 orbitals of the daughter ion. The neutrinoless electron-production mode 0nEPb-, which would manifest through a monoenergetic peak at the endpoint of the single-electron energy spectrum, is shown to be out of reach of the currently planned experiments. Conversely, its two-neutrino counterpart 2nEPb- might have already influenced the single-electron spectra measured, e.g., for the isotope 100Mo in the experiment NEMO-3. We discuss the prospects for detecting these new modes also for 82Se in its forthcoming successor SuperNEMO.
