,The Gel’fand-Levitan-Jost-Kohn Method, the radial Schr?dinger equation, is that of Gel’fand and Levitan, and Jost and Kohn, and is the subject of the present chapter. The second method is that of Marchenko, which uses the Jost solution. It will be studied in the following chapters. Each one has its own advantages, and permits us to clar

Examples,.. In fact, in the third section of chapter IV we studied an even more general case consisting of an initial arbitrary potential for which everything is known, and an increment which has the effect of multiplying the initial Jost function by a rational function of ..

Special Classes of Potentials,roblem for them can be dealt with either by the Gel’fand-Levitan or by the Marchenko method, a special technique has been found by Martin which permits solving the direct as well as the inverse problem by an iterative method based on special properties of the Laplace transform. We follow his method.

Scattering Amplitudes from Elastic Cross Sections,relations on scattered particles at different space-time points. The interest of such measurements has been pointed out by Goldberger et al. (1963, 1964, 1965, 1966), following Hanbury Brown and Twiss (1954, 1956). They proved that, with this technique, it is possible to explicitly measure the phase

The next step in studying the interaction is to introduce a mathematical model in which the interaction appears as a parameter, and to determine that parameter from ., cos θ). Such is the Schr?dinger equation with a spherically symmetric potential . in

In the first kind of approach, one risks obtaining potentials that violate certain fine physical requirements. In the second kind, one
