This manuscript (in a slightly modified form) has been considered 'too mathematical' for publishing in Physical Review A, 'too trivial' for the Journal of Mathematical Physics, and 'too narrowly focused' for the American Journal of Physics. Does all this mean that the paper is not interesting, not instructive, not scientific? I am not quite sure, but the reader can decide himself/herself

An example of full solution of the inverse scattering problem on the half line is presented. For this purpose, a simple analytically solvable model system (Morse potential) is used, which is expected to be a reasonable approximation to a real potential. First one calculates all spectral characteristics for the fixed model system. This way one gets all the necessary input data (otherwise unobtainable) to implement powerful methods of the inverse scattering theory. In this paper, the multi-step procedure to solve the Marchenko integral equation is described in full details. Excellent performance of the method is demonstrated and its combination with the Marchenko differential equation is discussed. In addition to the main results, several important analytic properties of the Morse potential are unveiled. For example, a simple analytic algorithm to calculate the phase shift is derived.
