- Abstract
The Multichannel Quantum Defect Theory and the Reduced R-Matrix are formally related and physically equivalent; both theories describe not only the internal dynamics but also the interactions in space of eliminated channels. One proves the Multichannel Quantum Defect Theory is Reduced Collision Matrix describing effect of eliminated channel on observed ones. The multichannel resonances originating in bound or quasistationary single particle states are described in terms of Reduced Collision Matrix. The single particle states are defined by Bound- or Quasistationary-State equation in the eliminated channel, relating channel logarithmic derivative to R-Matrix.
