A hydrogen atom starts out in the following linear combination of the stationary states 2, 1, 1> and 2, 1, -1>: Psi (, 0) = 1/sqrt(2) * (Psi (211) + Psi (21-1)) a) Construct Psi (, ) ; simply as much as you can. (5 points) b) Find the expectation value of the potential energy in units of eV. (10 points) c) Compute the energy expectation value of the system in units of eV. (5 points)
