Hello everybody, I am a first year physics student and I have a question about Nuclear Beta Minus Decay. I was thinking the other day, about a beta decay. After the nucleus is formed, the new atoms state is a positive ion with charge +1. If we think of the electron escaping from somewhere close to the nucleus the electron will be pulled by the nucleus. Is that electron bound at any time at all, or not? I understand that the function that describes the acceleration of the electron is going to be very weird, but I just care about the final kinetic energy of both. Also what happens to the rest of the electrons? How are they going to react in such a case? Do any of they emit photons? Do we usually have collision between that electron and the 'bound' electrons?
