ABSTRACT
An eigenfunction expansion for Green’s function, G(r,r′), for the geometry shown in Fig. 17.1 can now be obtained by substituting the corresponding form for the reduced Green’s function, (17.62), into (13.23). The Bessel function of zeroth order, J 0 (16.67), is introduced upon performing the angular integration associated with k⊥, so that Green’s function becomes
