  9. See, in particular, the examples considered in ref. (8). These difficulties were first pointed out to us byJ. L. Basdevant (private communication).

  10. We consider, for the sake of simplicity, the single-channel scattering of two spinless particles in state of orbital angular momentuml. The indexl has been suppressed throughout. The quantitiesp, p′, k andq refer to the magnitudes of the c. m. momenta and have the range 0≤p≤∞, etc. This last domain is also the range of all the integrations appearing in this paper. Finally, we suppose that the partial-wave amplitudes of the potential,V(p, p′), are symmetric inp, p′ which, in turn, implies a similar symmetry fort4(p, p′); the potential is presumed to be Hermitian.

  11. It is not clear how this freedom could be exploited in the course of a multiparticle calculation.
