Description
Summary:The change in the configuration of valence protons between the initial and final states in the neutrinoless double-\(\beta\) decay of \(^{130}\)Te \(\rightarrow\) \(^{130}\)Xe and of \(^{136}\)Xe \(\rightarrow\) \(^{136}\)Ba has been determined by measuring the cross sections of the (\(d\),\(^3\)He) reaction with 101-MeV deuterons. Together with our recent determination of the relevant neutron configurations involved in the process, a quantitative comparison with the latest shell-model and interacting-boson-model calculations reveals significant discrepancies. These are the same calculations used to determine the nuclear matrix elements governing the rate of neutrinoless double-\(\beta\) decay in these systems.
