摘要：

Formulae determining Regge pole positions and residues are derived within the phase-amplitude method. Numerical calculations are performed for an optical Lennard-Jones (12, 6) potential using parameters approximating elastic scattering of K, and Li, by HBr. Comparison with previous investigations shows that the phase-amplitude results are very accurate. Hence, the phase-amplitude method provides an important alternative to other methods used to investigate scattering problems in the complex angular momentum representation.
