The Stark effect here evidently includes both linear (a x) and quadratic (e x^2) contributions. It is usually treated by perturbation theory. The Stark effect with just the linear contribution can be solved exactly in parabolic coordinates. The quadratic part can then be treated as a perturbation.

is there any way to solve it using frobenius power series method ??
