Enss V., Weder R. Inverse Potential Scattering: A Geometrical Approach (163K, Postscript) ABSTRACT. In multidimensional short-range potential scattering the high energy limit of the scattering operator determines the potential uniquely. For given long-range potential the high energy behaviour of the Dollard modified scattering operator determines the potential uniquely. We use geometrical, time-dependent methods for the proof and obtain a reconstruction formula as well. AMS-LaTeX file and dvi file available by anonymous ftp 134.130.161.65
