Inverse Problem of Quantal Potential Scattering at Fixed Energy

The inverse problem of quantal scattering is a problem of long standing. However, despite an extensive literature (cf. the reviews [1, 5]) it seems that only recently has interest been directed toward practical applications, at least as far as the fixed-energy case is concerned [6, 8, 10, 12, 14]. The present work is a contribution to these efforts.
