A primary step in many attempts to ascertain the interaction potential between two colliding quantal systems is to define a “physical” S matrix (or scattering phase shifts) from measured data. We study applications of a controlled random search method of defining such S matrices. This method is model independent and should yield a global minimum form of the S matrix in the sense of a mean square variance in relation to the data. In practice, that is a difficult prospect. In this study, Woods-Saxon potentials, typical of those used in nuclear scattering data analyses, have been used to define the analytic input data for S-matrix analyses. The requirements on that input data with respect to re..
