Abstract
The nuclear matrix elements of Ge-76 and Se-82 are studied by using th e shell model wave functions in a model-space approximation. The influ ences of both nuclear short-range correlation and finite nucleon size on the transition matrix elements are also taken into account. The lim its of Majorana neutrino mass and mixing parameter of right-handed cur rent have been deduced by fitting the experimental values of 0nubetabe ta decay lifetimes of Ge-76 and Se-82.
