Abstract
Uncertainties in the nuclear transition matrix elements and of the double-positron emission and electron-positron conversion modes due to the exchange of light and heavy Majorana neutrinos, respectively, are calculated for Ru, Pd, Cd, Xe, Ba and Dy isotopes by employing the PHFB model with four different parameterization of the pairing plus multipolar two-body interactions and three different parameterizations of the Jastrow short range correlations. In all cases but for Ba, the uncertainties are smaller than 14% for light Majorana neutrino exchange and 35% for the exchange of a heavy Majorana neutrino.
