# Determination of the physical scattering matrix from a complete set of ambiguous solutions of the scattering problem by using the shortest-path method

## Description

Title of program: TPSPM Catalogue Id: AATW_v1_0 Nature of problem There are, in general, many ambiguous solutions for the scattering matrix (S-matrix) which all reproduce the measured data in the same way. Physical considerations, however, lead to the conclusion that only one solution is the true physical solution. The continuity criterion can be used to discard unphysical solutions. This criterion is commonly expressed by the requirement that, in a given energy interval, the physical solution should be that solution for which the connection between solutions ...
