title = "Benchmarking 136Xe neutrinoless ββ decay matrix element calculations with the 138Ba(p,t) reaction",
abstract = "We used a high-resolution magnetic spectrograph to study neutron pair-correlated 0+ states in 136Ba, produced via the Ba138(p,t) reaction. In conjunction with state-of-the-art shell model calculations, these data benchmark part of the dominant Gamow-Teller component of the nuclear matrix element (NME) for 136Xe neutrinoless double beta (0νββ) decay. We demonstrate for the first time an evaluation of part of a 0νββ decay NME by use of an experimental observable, presenting a new avenue of approach for more accurate calculations of 0νββ decay matrix elements.",
