摘要：

Uncertainties in nuclear transition matrix elements M-(0 nu) and M-N((0 nu)) due to the exchange of light and heavy Majorana neutrinos, respectively have been estimated by calculating sets of twelve nuclear transition matrix elements for the neutrinoless beta beta decay of Zr-94,Zr-96, Mo-98,Mo-100, Ru-104, Pd-110, Te-128,Te-130 and Nd-150 isotopes in the case of 0(+) -> 0(+) transition by considering four different parameterizations of a Hamiltonian with pairing plus multipolar effective two-body interaction and three different parameterizations of Jastrow short range correlations. Exclusion of nuclear transition matrix elements calculated with the Miller-Spencer parametrization reduces the uncertainties by 10%-15%.
