Question:
How would you detect Bound State β Decay?

Answer:
Let me think about it a little?
The next day I said: You would get a signal in the photon detector, coincident with no signal in the electron (β) detector.
 
Most Importantly I did not say, “The detected photon would be the Bremsstrahlung from the electron as it stops within the atom's vicinity.”

Given that the 2022 Nobel Prize in Physics has yet to be nullified and or rescinded, correctly describe the process known as Bound State β Decay.
