We present a quantum-defect theory (QDT) for the -1/r(4) type of long-range potential, as a foundation for a systematic understanding of charge-neutral quantum systems such as ion-atom, ion-molecule, electron-atom, and positron-atom interactions. The theory incorporates both conceptual and mathematical advances since earlier formulations of the theory. It also includes more detailed discussions of the concept of resonance spectrum and its representations, universal properties in charge-neutral quantum systems, and a QDT description of scattering resonances that is applicable to any -1/r(n) potential with n > 2.
