A hydrogen atom is placed in a constant electric eld in the positive zdirection. The perturbation is given by H 1 = e  E  z , where  E  is the magnitude of the electric eld and e is the electric charge of the electron. The electric eld is suciently strong that the relativistic and spinorbit eects can be neglected. Use the degenerate state perturbation theory to determine the rst order changes in energy eigenvalues of the n = 2 states. What are the corresponding new eigenfunctions?...
