Abstract
We present a general formulation of the quantum-defect theory for systems with an attractive type of asymptotic potentials with . Its structural differences from the standard theory for , or from the semiclassical theory, is fully explained through a systematic understanding of quantum reflection above the threshold, and quantum connection formulas below the threshold.
