Analysis of the Intermediate-State Contributions to Neutrinoless Double β⁻ Decays

Table 1

Most important multipoles and intermediate states contributing to the ground-state-to-ground-state 0 decays mediated by the light neutrino exchange. Columns give the energies (in MeVs) and multipoles of the intermediate states. Multipoles are organized from left to right in terms of their importance, the most important being on the left. Columns labeled give the corresponding NME contributions. Last two numbers in each column give the summed contribution and the percentual part which the displayed states give to the total multipole strength. The percentage inside the parenthesis gives the fraction with which the displayed states contribute to the total NME.
