摘要
We report a new direct method for calculating Regge pole positions and residues. Upon introduction of an absorbing optical potential sufficiently far in the asymptotic region, the problem reduces to several iterative diagonalizations of a symmetric complex matrix. The method is tested on well-studied cases of potential scattering.
