20. For our ergodic systems, statistics at long times (final α -decay) is not reliable since we adapted the duration of our measurements to reach only a consistent description of the first and second beta decays. However, the MCT solutions show the predicted stretched exponential decay f ( qp,τ) exp (-(τ) β ), where β=0.82±0.02.
21. We found that our nonergodic systems aged only in the first few hours after tumbling. Then, after a waiting time of one day, we performed independent measurements separated by one day finding no evolution due to aging effects within the time window of the measurements.

32. The emergence of tσ in both the time and frequency domain descriptions is accounted for by the very nature of the Fourier transformation. On one hand, tσ is the characteristic time associated to the beta decays: f (qp, τ)-f (qp,∞) (τ/tσ)-a and f (qp, τ)-f (qp,∞) (τ/tσ)b. On the other hand, via Fourier transformation, the frequency tσ -1 appears as the characteristic counterpart in the frequency domain description given by Eqs.
