Exchange contribution to the variance of the excitation energy of the electron shell of the daughter atom in double- decay
K. S. Tyrin, M. I. Krivoruchenko
The excitation of electron shell of a daughter atom in a neutrinoless double -decay causes change in shape of the total energy peak of electrons at the end of the energy spe…
