Consider the delta function potential well :V(x) = −αδ(x) (α > 0).
(a) What are the boundary conditions on the bound state wave function and its derivative at x = ±∞ and x = 0? Explain. Hint: You may find the property stated in Prob. 2 useful.
(b) Show that there is only one bound state.
(c) Find the energy E and wave function ψ(x) of the bound state.
(d) Find the transmission coefficient for scattering states, with energy E > 0 and incident form the left
