Show affiliationsQuantum defect theory can be used to convert energy shifts of hadronic atoms into zero-energy scattering lengths (and vice versa). The scattering lengths from quantum defect theory are in good agreement with those derived using all-order Deser-Trueman formulae (evaluated by the simple expedient of evaluating the left-hand side of the effective range expansion exactly). Scattering lengths derived from experimental energy shifts are presented for a number of hadronic atoms.
