摘要：
We discuss the 0nubetabeta decay mediated by a light neutrino. Two-nucleon mechanism and shell-model wave function are used in this paper. Also we take into account the influences of both nuclear short-range correlation term and finite nucleon size on the calculations of transition matrix elements. The relation between the mixing parameter eta of right-handed current and the Majorana neutrino mass m(nu) is obtained by fitting the experimental data of 0nubetabeta decay lifetimes of Ge-76 and Se-82.
