Within the framework of the eigenchannel reaction theory above the two-particle thresholdcluster channels are introduced. The eigenchannels of the S-matrix are used, i. e. continuum stateswhich diagonalize both the S-matrix and the nuclear Hamiltonian and represent for each reactionenergy a discrete set of coupled channel wave functions with a common (eigen-) phase. Especiallythe emission of a deuteron is discussed. It is shown that the cluster channels supplement the energy-correlated channels describing the energy partition £1 + e2 = E —Ef and that asymptotic channelorthogonality holds. The characteristic feature of the cluster channels as compared to the energy-correlated channels is that their final state interaction is not limited to a finite matching volumecomparable to nuclear sizes.
