Consider a one-dimensional potential fσ(x) = (2πσ)^(-1/2)e^(-x^2/(2σ)). In the limit σ → 0, this potential is just the δ(x) function potential. Suppose that we now set σ = 0.001, and solve the Schrödinger equation for the scattering states. Which of the following conditions should the wave function ψ(x) for the scattering state satisfy at x = 0?
