    "abstract": "A recently proposed method based on dispersion theory, that allows to extract\nthe scattering length of a hadronic two-body system from corresponding\nfinal-state interactions, is generalized to the situation where the Coulomb\ninteraction is present. The steps required in a concrete practical application\nare discussed in detail. In addition a thorough examination of the accuracy of\nthe proposed method is presented and a comparison is made with results achieved\nwith other methods like the Jost-function approach based on the effective-range\napproximation. Deficiencies of the latter method are pointed out. The\nreliability of the dispersion theory method for extracting also the effective\nrange is investigated.",
