1).a) Show that the bound state wave function ψb (Eqn 2.129) and
the continuum state wave
function ψk (Eqn 2.131-132 with coefficients 2.136-137) are
orthogonal, i.e., 〈ψb|ψk〉 = 0. (b)
[bonus] Explain why the orthogonality exists, example as, are they
eigenstates of an operator? If so,
what is the operator? If not explain.
