Localization of shadow poles by complex scaling
arXiv:nucl-th/9305001 · doi:10.1103/PhysRevA.48.3390
Abstract
Through numerical examples we show that the complex scaling method is suited to explore the pole structure in multichannel scattering problems. All poles lying on the multisheeted Riemann energy surface, including shadow poles, can be revealed and the Riemann sheets on which they reside can be identified.
