Sharp, J. F. Smith, and I. Stefan In neutrinoless double- β decay such as 136 Xe to 136 Ba, two neutrons become two protons, thus rearranging the occupancy of protons and neutrons in the ground states of the parent and daughter nuclei. From precision measurements of the cross sections of single-neutron adding and -removing reactions, the authors extract the change in ground-state neutron occupancies between 136 Xe and 136 Ba. Along with recent results on the proton occupancies, the new experimental neutron occupancies disagree with those used in existing theoretical calculations of the rate of this elusive β -decay mode, and provide a basis for improved estimates of the uncertainties for new calculations.
