摘要：

We propose a method to determine the singularity parameters of the scattering amplitude given through data. The stabilizing smoothness norm acts as indicator of the most likely positions of poles in the unphysical sheets. We apply the method to experimental data on the ππ and πK partial waves. © 1979 The American Physical Society.
