Examples of non-uniqueness in one-dimensional inverse scattering for which \(T(k)=O(k^ 3)\) and \(O(k^ 4)\) as k\(\to 0\). (English) Zbl 0625.35074

An example of a one-parameter family of potentials in one-dimensional non-relativistic quantum mechanics is given such that all the potentials in the family have the same scattering matrix at all energies and the transmission coefficient behaves like \(T(k)=O(k^ 3)\) as \(k\to 0\). An example where \(T(k)=O(k^ 4)\) as \(k\to 0\) is also given.
