Multiparticle scattering theory and the method of coupled reaction channels

Nuclear Physics A, 1982
Abstract The two-Hilbert-space formulation of multiparticle scattering theory is used to investigate the validity and limitations of the conventional form of the coupled reaction channels (CRC) method. Also a new set of coupled dynamical equations is rigorously derived which includes the conventional CRC equations as a special case.

The non-orthogonality problem of the coupled reaction channels method

Zeitschrift f�r Physik A Atoms and Nuclei, 1983
The coupled reaction channels method is formulated as a two-step procedure. In the first step, the eigenvalue problem of the overlap operator is solved. In the second step, an off-shell transformation is applied to the coupled reaction channels equation. The transformed equation has an energy-independent interaction.

Generalized Feshbach projection operator method and the coupled reaction channel formalism

Physical Review C, 1982
The multichannel generalizations of the Feshbach formalism are considered. These generalizations are nonunique. We demonstrate the equivalence of two such generalizations and show that they reduce to the familiar coupled reaction channel formalism under certain approximations.

Breakup Amplitudes from the Pseudostate Extension of the Coupled-Reaction-Channels Method

Few-Body Systems
A pseudochannel extension of the coupled-reaction-channel (CRC) ansatz had been used in earlier work to simulate the effect of the breakup channel on the rearrangement amplitudes. Comparisons with benchmark results on model systems established that rearrangement amplitudes and total breakup probability could be obtained accurately.However, achieving ...

Reexamination of the coupled-reaction-channels method: Derivation from the triad of three-particle Lippmann-Schwinger equations and its use with separable resolvent expansions

Physical Review C
An interesting connection is found between the coupled-reaction-channel (CRC) approach and the triad of Lippmann-Schwinger (LS) equations for the three-particle scattering state. It turns out that the CRC decomposition ansatz can be used as a vehicle to couple the three uncoupled LS equations.
