In the case of a 0+ to 0+ transition, my copy of Krane's Introductory Nuclear Physics says that this is an electric monopole transition (E0), and it can happen when an even-even nucleus transitions from an excited 0+ state to a 0+ ground state. Although there is no radiation field for this transition beyond r > R, at r < R (i.e., inside the nucleus) there is a monopole distribution where the potential does fluctuate, and this is what is sampled by the electron. I take from this that the electron will not feel anything outside of the nuclear volume since the E0 radiation field cancels out at r > R. (Here we've started to venture beyond my understanding of the topic.) Eric
