The problem of finding the energy levels of an atom is solved under the assumption that the nucleus has a point charge; in fact, the nucleus has a finite size: its radius is R = 1.3 • 10-13A1/3 cm, where A is the atomic mass. Estimate the sign and order of magnitude of the relative correction to the muon energy DE/E on the K-shell of neon (Z = 10, A = 20), associated with the fact that part of the time the muon is inside the nucleus, i.e. in a field different from the Coulomb field. The wave function of the ground state of an electron in a hydrogen atom has the form y = (naB3)
