| Abstract: | The transition operator T for the scattering of a particle from N potentials Vj(x) can be expanded into a series featuring the transition operators tj associated with the individual potentials. For Vj(x) both absolutely and square integrable in x, we show, using an analytic continuation argument, that if T is on-shell, i.e. in 〈k|T(k02±i0)|k′〉, |k| = |k′| = k0, then each tj is also on-shell. |
