✦ Synopsis

The decoupled Yakubovski equation is brought into an amenable form under some approximations. As the result, the number of equations to be solved is considerably reduced from the original Yakubovski equation. The whole equation becomes very close to the equations in the conventional reaction theories. The relevance to the optical potential, DWIA and the impulse approximation are discussed. In the present theory, the persistence of the channel wavefunctions in the course of multiple scatterings is not presumed. The channel wavefunctions can collapse under two-body interactions. Nevertheless, we see that the most important process is the particle transfers between bound clusters. Once the channel wavefunction is collapsed it is very difficult to revive again as a channel wavefunction. This part may be interpreted as forming a compound system.
