Figure 1 - Quantum square-well with logarithmic central spike

The shapes of the perturbed square-well potentials (8) at g = 1/4 (the lowest, light spike), g = 1/2 (the intermediate spike) and g = 1 (the upper spike). Horizontal lines mark the first two energy levels for g = 0. Attached to them, the picture also displays the shapes of the unperturbed wave functions.
