The Lamb Shift
A P orbital is closer on average to the nucleus than an S orbital for a given atom, and the electron has additional curvature as it arcs in an attractive Coulomb field. A hydrogen electron in an S orbital therefore absorbs more gravitons in a single arc than the same electron when in a P orbital, both because it is on an arc of less curvature and because the arc is longer in distance than in the P orbital.
As an electron in an atomic orbital passes its closest to the nucleus it continues to exist in a graviton absorption mode and, if traveling toward a gravitational source, continues to increase in mass, magnetic dipole moment, and charge until it comes time to make a turn. This is likely the reason why Willis Lamb found in 1951 a greater energy in the 2S1/2 orbital compared to the 2P1/2 orbital.* The electron in the 2S1/2 orbital would be slightly larger in diameter on average and carry a slightly more negative charge on average compared to the electron in a 2P1/2 orbital.
It may be that the Coulomb force within an atom is not photon mediated as originally thought, but rather due only to magnetic field vectors which could not be produced continually without the nucleus and orbiting electrons absorbing gravitons.
