An electron outside a dielectric is attracted to the surface by a force, F = -A/x2, where x is the perpendicular distance from the electron to the surface, and A is a positive constant. Electrons are prevented from crossing the surface, as there aren't any quantum states in the dielectric for them to occupy. Suppose that the surface is infinite, so that the problem is 1-dimensional. Write the Schrodinger equation for an electron outside of the surface (x > 0) and determine the appropriate boundary condition at x = 0. Obtain a formula for the allowed energy levels of the system. (Hint: Compare the equation for the wave function Ψ(x) with that satisfied by the wave functinon u(r) = rR(r) for a hydrogenic atom.)
