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

Figure 6

Cumulative values of the l-NMEs for ground-state-to-ground-state decays of the nuclei ¹⁰⁰Mo and ¹¹⁶Cd ((a) and (b) panels), and for the ground-state-to-excited-state decays of the nuclei ⁸²Se and ⁹⁶Zr ((c) and (d) panels). The horizontal axis gives the excitation energies of the intermediate states contributing to the transition. Two different values for the axial coupling were used as indicated in the panels.

(a) ¹⁰⁰Mo()

(b) ¹¹⁶Cd()

(c) ⁸²Se()

(d) ⁹⁶Zr()
