Electron in an l=+1,0,-1 state "hopping" If a single electron is a point-like particle as needed by the Dirac Equation, and it is occupying an l=+1 state, how does the point like particle get from the charge density region above the nucleus down (over) to the lower charge density region? Both regions are occupied with equal probability, but a point charge is a point charge and to equally occupy the other region a point charge has to move (hop) very quickly to the opposing region and then back again. How does a point charge do that? Most importantly what PATH in space does it take? Does it physically hop back and forth between the upper density region to the lower density region? Does it pass through the nucleus? Does it avoid the nucleus and hop around the nucleus?
