Question

This is a multi-step problem. I already solved the first one: Assuming that the alpha particle moves along a diameter of the nucleus and that it moves at low enough speed that relativistic effects are negligible, what is the time between successive encounters between each edge of the nucleus and the alpha particle?

but I can't figure out the second one: In a given period of time, what is the probability that the nucleus has decayed? answer in terms of T, t, and delta t

Any help would be appreciated. Thanks

Explanation / Answer

first answer: 2r/[sqrt(2E/m)^1/2]
