Simple question, please help. I think it belongs in this forum, though I apologize if there's a nuclear physics forum or somewhere else I should put this.
I came across this thread when trying to figure out why electrons don't rest at zero distance away from the nucleus of an atom.
So as I understand it (please correct me if I'm wrong) HUP says [tex]\Delta x \Delta p \geq \frac{\bar{h}}{2} [/tex] so if you try to confine an electron to the nucleus Δx becomes small so that Δp becomes large, and an increased spread in p leads to an increased kinetic energy so there's an energy requirement or "pressure" involved in confining an electron to within, say, a proton.
Now, the above thread outlines a problem (homework probably) that is meant, I believe, to show that thinking of a neutron as an electron embedded into a proton waiting to tunnel away as Beta radiation is incorrect. There is too large a deviation between the emission energy of an electron in Beta decay and the hypothetical electron's kinetic energy while bound inside a proton.
So my question is twofold:
1) Is my reasoning correct so far?
2) How ought I to think about a neutron and the process of Beta decay?
