Three-Dimensional Anisotropic Harmonic Oscillator An oscillator bas the potential-energy function U(x. y. z) = ½ k₁(x² + y²) + ½ k₂^’ z² where k₁ > k₂. This oscillator is called anisotropic because the force constant is not the same in all three coordinate directions. 

(a) Find a general expression for the energy levels of the oscillator (see Problem 40.53). 

(b) From your results in part (a) what are the ground-level and first x-cited-level energies of this oscillator? 

(c) How many states (different sets of quantum numbers n_x, n_y, and n_z) are there for the ground level and for the first excited level? Compare to part (c) of Problem 40.53.
