Abstract content <br> &nbsp; (Max 300 words)

The problem of extracting spectral points(bound and resonant states) from scattering data, obtained experimentally or theoretically, is addressed. A new fitting strategy, incorporating an evolution algorithm, is outlined. The fitting parameters are the coefficients of a semi-analytical expression derived from the multi-channel Jost-matrix done near an arbitrary point on the Riemann surface. The efficiency and accuracy of the suggested expansion and fitting is demonstrated by an example of a one-channel model.
