AbstraktAbstract
It is possible to calculate nuclear matrix elements of neutrinoless double-beta decay using virtual decay paths with two-particle transfer under well-known the closure approximation. The nuclear matrix elements are calculated using the proton-neutron quasiparticle random-phase approximation (QRPA) for the original double-beta path and the like-particle QRPA for the two-particle-transfer path. I determine the strength of the isoscalar proton-neutron pairing interaction so as to obtain the same nuclear matrix elements by the two calculations. The consistency of the QRPA approach is improved by this method.
