npub1kpwlxpzkxfmuxjmzc2wp3rf9vjg0sgydmlhsnrgqr3maf59h86qqdxxzz4 (npub1kpw…xzz4) At a quick guess, you're close, but it's energy, not moment. The nuclear decay processes are very short range and all the electrons know about it is via electromagnetism (since they don't participate in the strong interaction, the weak interaction is too short-range, and the electron's mass is too small for gravity to be important). If you want the electrons to leave their orbitals, you need to pump some energy into them. The less-negative electromagnetic potential energy from the reduced nuclear charge isn't necessarily enough for that to happen quickly - the atom just exists as a -2 ion for long enough that the alpha particle has time to escape.

I'm not a particle physicist; just trying piece together what I remember from undergrad physics.
