Imagine applying a weak static electric field to a hydrogen atom.
i) To 1st order in perturbation theory, what is the change to the 1s orbital energy?
ii) Without working all the way through the details, show that the 2nd order energy correction will be fundamentally different than the 1st.

Let Ho be the Hamiltonian of the non-relativistic hydrogen atom neglecting spin. Consider H1 = e|E\r cos 0 with e|E|af < 1. This Hamiltonian describes a weak constant electric field in the z-direction interacting with the atomic dipole. We want to understand the effect such a field has on the first excited energy level, E2, of hydrogen. Remember that this energy level is degenerate with corresponding eigenstates |2lm) Use first-order perturbation theory to find the aproximate energies of Ho+ H1...

2. In the derivation of the energy levels in the hydrogen atom one commonly assumes that the nucleus is a point charge. However, in reality the size of the nucleus is of the order of Im = 10-15m. Since this is very much smaller than the typical distance of the electron from the nucleus, which is of the order of a0-0.5A = 0.5 × 10-10m, the finite size of the nucleus can be taken into account perturbatively. (a) Assume that...
