The first objective is to analyse the scattering matrix corresponding to this potential. We show that it includes a series of poles corresponding to the types of redundant poles or anti-bound poles. In some cases, there are even bound states and this depends on the values of given parameters. Then, we perform different supersymmetric transformations on the original Hamiltonian using either the ground state (for those situations where there are bound states) wave functions, or other solutions that come from anti-bound states or redundant states. We study the properties of these transformations. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2023 The Author(s) Atribución 4.0 Internacional SUSY partners and S-matrix poles of the one-dimensional Rosen–Morse II potential info:eu-repo/semantics/article
