... where the radius a of the electron cloud is taken to be 0.5 Å. The forces which keep the protons and neutrons bound in the nucleus are very different from and much stronger than the Coulomb forces acting between electric charges. Indeed, neutrons have no charge, and therefore no Coulomb field. Neve ...

We find that the change in energy of the vacuum electrons from the initial to final state is zero. This is true for any electric potential. However ...
