Abstract
Quantum defect theory can be used to convert energy shifts of hadronic atom s into zero-energy scattering lengths (and vice versa). The scattering leng ths from quantum defect theory are in good agreement with those derived usi ng all-order Deser-Trueman formulae (evaluated by the simple expedient of e valuating the left-hand side of the effective range expansion exactly). Sca ttering lengths derived from experimental energy shifts are presented for a number of hadronic atoms.
