Find the energy spectrum of a particle in the infinite square
well, with potential U(x) → ∞ for |x| > L and U(x) = αδ(x) for
|x| < L. Demonstrate that in the limit α ≫ hbar^2/mL, the low
energy part of the spectrum consists of a set of closely-positioned
pairs of energy levels for α > 0. What is the structure of
energy spectrum for α < 0?
