We have made the nuclear shell-model calculations of the 0nubetabeta decays in Ge-76 and Se-82 using a model-space approximation. Also we take into account the influences of both nuclear short-range correlation and finite nucleon size on the calculations of the transition matrix elements. The limits of Majorana neutrino mass and mixing parameter of right-handed current have been deduced by fitting the experimental values of 0nubetabeta decay lifetimes of Ge-76 and Se-82.
