Jeffreys Born Approximation

The partial wave scattering analysis gives the following modified Bessel Equation:

$\left[{\frac {d^{2}}{d^{2}r}}+k^{2}-{\frac {l(l+1)}{r^{2}}}\right]\Psi _{l}(r)=U(r)\Psi _{l}(r)$

where $k^{2}$ is the energy, $l$ is the eigenvalue of the angular momentum operator $L^{2}$ and $U(r)$ is the interaction potential. With the help of the outgoing Green's Function $G_{l}^{+}(r,r')$, the solution of this equation is

$\Psi _{l}(r)={\tilde {\Psi }}_{l}^{(0)}+\int _{0}^{\infty }{G_{l}^{+}(r,r')U(r')\Psi _{l}(r')dr'}$

where ${\tilde {\Psi }}_{l}^{(0)}$ is the solution of the unperturbed Bessel equation with $U(r)=0$. As you can see, the solution $\Psi (r)_{l}$ appaears on both left and right of the last equation. An iterative solution to this problem is by successive substitution into the integrand, of the same expression $\Psi _{l}^{(0)}$:

${\begin{aligned}\Psi _{l}^{(0)}={\tilde {\Psi }}_{l}^{(0)}(r)&+\int _{0}^{\infty }{G_{l}^{(+)}(r,r')U(r'){\tilde {\Psi }}_{l}^{(0)}(r')dr'}\\&+\int _{0}^{\infty }\int _{0}^{\infty }{G_{l}^{(+)}(r,r')U(r')G_{l}^{(+)}(r',r'')U(r''){\tilde {\Psi }}_{l}^{(0)}(r'')dr'dr''}+...\\\end{aligned}}$

or in a short notation:

$\Psi _{l}=(1+G_{l}^{(+)}U+G_{l}^{(+)}UG_{l}^{(+)}U+...){\tilde {\Psi }}_{l}^{(0)}$
