Homework Statement
Consider the Hamiltonian for a rigid rotator, constrained to rotate in xy plane and with moment of inertia I and electric dipole moment[itex]\mu[/itex] in the plane, as [itex]H_0=\frac{L_z^2}{2I}[/itex]. Then suppose that a constant and weak external electric field,[itex]E[/itex], in the direction of x is applied so the perturbation is [itex]H'=-\mu E cos (\phi)[/itex].
Homework Equations
The eigenfunctions of [itex]H_0[/itex] are double degenerate and the degeneracy is not removed even in high orders of perturbation. How should I solve it? could anyone please help me?
