Claims

C1strongest claim

The half-life of the single beta decay of 96Zr is measured to be T_{1/2} = [2.27^{+0.53}_{-0.36}(stat) ± 0.27(syst)]×10^{20} yr.

C2weakest assumption

The detected gamma-ray cascade originates specifically from the beta decay of 96Zr to 96Nb followed by 96Nb decay to excited states of 96Mo, rather than from unrelated background processes or other isotopes.

C3one line summary

First observation and half-life measurement of single beta decay in 96Zr at T1/2 ≈ 2.27 × 10^20 years via gamma-ray cascade from daughter 96Nb.
