Strength of J π = 1 + Gamow-Teller and isovector spin monopole transitions in double-β-decay triplets

In this work we study systematically the energetics and intensity distributions of Gamow-Teller (GT±) and isovector spin monopole (IVSM±) transitions from the ground states of the pairs (76Ge,76Se), (82Se,82Kr), (100Mo,100Ru), (116Cd,116Sn), (128Te,128Xe), (130Te,130Xe), and (136Xe,136Ba), of double...

description In this work we study systematically the energetics and intensity distributions of Gamow-Teller (GT±) and isovector spin monopole (IVSM±) transitions from the ground states of the pairs (76Ge,76Se), (82Se,82Kr), (100Mo,100Ru), (116Cd,116Sn), (128Te,128Xe), (130Te,130Xe), and (136Xe,136Ba), of double-beta-decay initial and final nuclei, to the J π = 1+ excited states of the intermediate odd-odd nuclei 76As, 82Br, 100Tc, 116In, 128,130I, and 136Cs. We use a proton-neutron quasiparticle random-phase approximation (QRPA) theory framework with the Bonn-A two-body interaction in large no-core single-particle valence bases. Our studies indicate that the GT−strength at the giant resonance (GTGR) region and the low-energy part of the IVSM− strength overlap, which could be of significance for the analyses of the (p,n) type of reaction experiments at and around the GTGR.
