摘要：
Matrix elements for 0nubetabeta decay of Ge-76, Se-82, Cd-116, Te-128, Te-130, Xe-136 and Nd-150 are calculated combining proton-neutron quasiparticle RPA wave functions with the operator expansion method (OEM). The differences between OEM and earlier QRPA calculations, using the closure approximation, are investigated in detail. Special emphasis is put on the discussion on the differences between the 2nubetabeta and the 0nubetabeta mode, since currently 0nu matrix elements can only indirectly be tested. By a comparison with experimental data upper limits on the effective neutrino mass are derived.
