23. To be rigorous, one ought to introduce integrations over the momenta of the spectator particles in Eq. (2.2). Since these integrations are removed when considering the momentum-space matrix elements of the relevant transition operators, to save on notation here and in the following we shall leave such integrations implicit.

27. Strictly speaking, because of the identity of the nucleons, one has a unique transition amplitude for the process (Formula presented). As usual in scattering theory, for the moment we assume the nucleons as distinguishable, so that the configurations (Formula presented) and (Formula presented) are regarded as different from each other. The prescriptions due to particle identity can be taken into account at the end, through suitable linear combinations of the transition amplitudes. However, to save on notation, we shall simply write (Formula presented) in place of (Formula presented) in the transition amplitudes.
