What can one say about the integrability of solutions of the time-independent Schroedinger equation Hψ=Eψ, where H=p2/2m+V(x), with V(x)=W(x)2?
a) For bound states, ψ is square integrable. Is the same true for pψ? For W(x)ψ?
b) For scattering states? Here ψ is not square integrable. What are the requirements on ϕ such that ⟨ϕ|ψ⟩ exists? Is the square integrability of Hψ enough? Or that of pψ and W(x)ψ?
Where can I find such questions discussed?
