摘要：

Employing four different parametrizations of the pairing plus the multipolar type of effective two-body interaction and three different parametrizations of the Jastrow type of short-range correlations, the uncertainties in the nuclear transition matrix elements M-N((0 nu)) due to the exchange of heavy Majorana neutrino for the 0(+) -> 0(+) transition of neutrinoless double 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 PHFB model are estimated to be around 35%. Excluding the nuclear transition matrix elements calculated with the Miller-Spencer parametrization of Jastrow short-range correlations, the uncertainties are found to be smaller than 20%.
