In the Fock-Tani representation for rearrangement collisions, the interaction Hamiltonian decomposes into terms representing interactions within each arrangement channel and channel-changing rearrangement interactions. The two-potential formalism is used to cast transition amplitudes into a distorted-wave form in which in-channel interactions are treated exactly and interchannel transitions in finite order, thus separating initial- and final-state interactions from rearrangements. Self-energies arising from infinite-order summations of selected interchannel transitions are also considered and illustrated by shifts and broadenings of scattering and reaction resonances.
