I've started researching an interesting phenomenon known as the Anti-Zeno Effect (AZE), where frequent measurements can induce an increase in the decay rate of an unstable quantum system. Multiple experiments have been done to prove this theory. However, as noted by this article attached down below, this AZE can also be used (theoretically) to speed up beta decay by frequently striking a decaying nucleus with a gamma ray source. Obviously, we would have to take into the account of time-energy uncertainty of the photons be shot at the decaying nucleus. My mathematical knowledge isn't high enough to understand the claim (as mentioned in equations 19 and 20 in the article), does anyone have an idea on how to put the equations presented into words? Any help would be greatly appreciated! EDIT: Specifically, if anyone could explain this statement that encompasses equation (20): Article Here: Acceleration_of_quantum_decay.PDF
