Two-neutrino ββ decay of 136Xe to the first excited 0+ state in 136Ba
We calculate the nuclear matrix element for the two-neutrino ββ decay of 136Xe into the first excited 0+ state of 136Ba. We use different many-body methods: the quasiparticle random-phase approximation (QRPA) framework, the nuclear shell model, the interacting boson model (IBM-2), and an effective f...
