Consider a hydrogen atom in an electric field of strength &. The Hamilto- nian operator for this system is H v². e2 +e&rcos 0. Απερ 2m a) Identify Ĥ0), Ĥ), ¥©, e0) for this problem. b) Now use the hydrogen atom as the unperturbed problem and the same perturbation oper- ator. Calculate the first-order perturbation contribution to the ground state energy for the hydrogen atom in an external electric field described this perturbation operator.
