Preserved Fulltext
We present a general formulation of the quantum-defect theory for systems with an attractive 1 / r ␣ type of asymptotic potentials with ␣ Ͼ 2. Its structural differences from the standard theory for ␣ Յ 2, 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.
