The standard coupled-reaction-channel formalism for nuclear rearrangement reactions is compared with bound-state approximations obtained by starting from modern N-body scattering theory. This comparison will allow us to clarify the origin of nonorthogonality terms in standard coupled-reaction-channel equations as well as the reason of their absence in N-body formalisms. Contributions neglected by the bound-state approximation are taken into account in a three-body context by introducing interacting-particle representations. Thus we can also establish interrelations between different three-body formalisms.

Abstract
The standard coupled-reaction-channel formalism for nuclear rearrangement reactions is compared with bound-state approximations obtained by starting from modern N-body scattering theory. This comparison will allow us to clarify the origin of nonorthogonality terms in standard coupled-reaction-channel equations as well as the reason of their absence in N-body formalisms. Contributions neglected by the bound-state approximation are taken into account in a three-body context by introducing interacting-particle representations. Thus we can also establish interrelations between different three-body formalisms.File in questo prodotto:
