摘要：

A microscopic state-of-the-art calculation of the nuclear matrix element for neutrinoless double-beta decay of Nd-150 with an account for nuclear deformation is performed. The proton-neutron quasiparticle random phase approximation (QRPA) with a realistic residual interaction [the Brueckner G matrix derived from the charge-dependent Bonn (Bonn-CD) nucleon-nucleon potential] is used as the underlying nuclear structure model. The present calculated matrix element is suppressed by about 40% as compared with our previous QRPA result for Nd-150 obtained with neglect of deformation. By making use of this newest nuclear matrix element, one may conclude that neutrinoless double-beta decay of Nd-150, to be measured soon by the SNO+ collaboration, provides one of the best probes of the Majorana neutrino mass.
