Pair correlations in the neutrinoless double-β decay candidate Te130
Pair correlations in the ground state of Te130 have been investigated using pair-transfer experiments to explore the validity of approximations in calculating the matrix element for neutrinoless double-β decay. This nucleus is a candidate for the observation of such decay, and a good understanding of its structure is crucial for eventual calculations of the neutrino mass, should such a decay indeed be observed. For proton-pair adding, strong transitions to excited 0+ states had been observed in the Te isotopes by Alford [Nucl. Phys. ANUPABL0375-947410.1016/0375-9474(79)90114-3 323, 339 (1979)], indicating a breaking of the BCS approximation for protons in the ground state. We measured the neutron-pair removing (p,t) reaction on Te130 and found no indication of a corresponding splitting of the BCS nature of the ground state for neutrons. © 2010 The American Physical Society.
