# Magnitude of resulting decay rates due to Anti-Zeno effects

Regarding the Quantum Anti-Zeno effect (AZE), we know that frequent measurements of a decaying system (such as a decaying radioactive nucleus) can induce greater decay rates.

However, if I understand correctly, you can change the percentage of change in the decay rate. For example, if you have condition x, you might only get a 2% increase in decay rate, however, with condition y you can get, say a 12% increase in decay rate.

The question is, what influences the percent of change from the original decay rate to the new decay rate in a system experiencing the Anti Zeno Effect?

I also have a second question: it has been proposed that to increase beta decay rates, one might shoot photons at the decaying nucleus in order to induce the AZE. What would be the variable here that would influence the percent of change, in this case, decay rate of the isotope?
