atomic levels.) In the strong field limit, the Stark effect is independent of electron spin. We start with the ordinary hydrogen Hamiltonian, H0 = p2 2m − e2 r and add a term arising from a uniform electric field along the z axis. H′ = eEz. Note the + sign on this term. It is easily checked by remembering that the force on the

The Stark e ect is the electric analogue to the Zeeman e ect, i.e., a particle carrying an electric dipole moment, like the H-atom, will get a splitting of its energy levels when subjected to an exterior electric eld.

As a more involved example of the level degeneracy lifting by a perturbation, let us discuss the Stark effect \(^{6}\) - the atomic level splitting by an external electric field. Let us study this effect, in the linear approximation, for a hydrogen-like atom/ion. Taking the direction of the external electric field
Thus, a first-order Stark effect analysis along the same lines as for hydrogen is then pertinent. As was the case with the Zeeman effect, the Stark effect will break the degeneracy in M J. This is to be expected, since again a field will impose a preferred direction, and will break spherical symmetry. However, as we will see, this time the ...
1. Introduction. In these notes we consider the Stark effect in hydrogen and alkali atoms as a physically interest-ing example of bound state perturbation theory. The Stark effect concerns the behavior of atoms in external electric fields.
Stark E ect. Robert Gilmore. Physics Department, Drexel University, Philadelphia, PA 19104. February 24, 2014. Abstract. An external electric eld E polarizes a hydrogen atom. This lowers the ground state en-ergy and also partly breaks the N2-fold degeneracy of the N2 hydrogenic states NLM(x) = hxjNLMi with principal quantum number N.
